In one embodiment, a multilayer structure comprises: an initial terpolymer layer, a second layer comprising plastic and/or glass, a polycarbonate layer, and an adhesive layer. The initial terpolymer layer comprises a polycarbonate terpolymer derived from a first dihydroxy compound, a second dihydroxy compound, and a third dihydroxy compound, the first dihydroxy compound has Structure (A) wherein Rf is a hydrogen or CH3; the second dihydroxy compound has Structure (A) and is different from the first dihydroxy compound; and the third dihydroxy compound does not have Structure (A), and wherein a sum of mole percent of all of the first dihydroxy compound and the second dihydroxy compound is greater than or equal to 45% relative to a sum of mole percent of all of the first dihydroxy compound, the second dihydroxy compound, and the third dihydroxy compound in the polycarbonate terpolymer.

1. A multilayer structure, comprising: an initial terpolymer layer comprisinga polycarbonate terpolymer derived from a first dihydroxy compound, a second dihydroxy compound, and a third dihydroxy compound, whereinthe first dihydroxy compound has Structure (A) wherein Rf is a hydrogen or CH3; the second dihydroxy compound has Structure (A) and is different from the first dihydroxy compound; andthe third dihydroxy compound does not have Structure (A), and wherein a sum of mole percent of all of the first dihydroxy compound and the second dihydroxy compound is greater than or equal to 45% relative to a sum of mole percent of all of the first dihydroxy compound, the second dihydroxy compound, and the third dihydroxy compound in the polycarbonate terpolymer;a second layer comprising plastic and/or glass;a polycarbonate layer, wherein the initial terpolymer layer is located between the polycarbonate layer and the second layer; andan adhesive layer located between the initial terpolymer layer and the second layer, wherein the adhesive layer comprises a material selected from the group consisting of PVB, EVA, and combinations comprising at least one of the foregoing. 2. The multilayer structure of claim 1, wherein the polycarbonate terpolymer comprises hydroquinone, methyl hydroquinone, and BPA. 3. The multilayer structure of claim 1, further comprising an additional terpolymer layer, wherein the additional terpolymer layer comprises a second polycarbonate terpolymer comprising structures derived from the first dihydroxy compound, the second dihydroxy compound and the third dihydroxy compound; and wherein the second layer comprises polycarbonate, and wherein the initial terpolymer layer is in physical contact with both the polycarbonate layer and the adhesive layer, and the additional terpolymer layer is in physical contact with both the adhesive layer and the second layer. 4. The multilayer structure of claim 1, wherein the initial terpolymer layer is in physical contact with both the polycarbonate layer and the adhesive layer, and the adhesive layer is also in physical contact with the second layer. 5. The multilayer structure of claim 1, wherein the initial terpolymer layer further comprises phosphoric acid or phosphorous acid. 6. The multilayer structure of claim 5, wherein the initial terpolymer layer comprises about 1 ppm to about 15 ppm phosphoric acid or phosphorous acid. 7. The multilayer structure of claim 6, wherein the initial terpolymer layer comprises about 8 ppm to about 12 ppm phosphoric acid or phosphorous acid. 8. The multilayer structure of claim 5, wherein the initial terpolymer layer comprises a sufficient amount of the phosphoric acid or phosphorous acid to attain, in the multilayer structure, a flexed plate impact retention at maximum force of greater than or equal to about 65% after two weeks of exposure to 70° C. and 95% relative humidity. 9. The multilayer structure of claim 8, wherein the flexed plate impact retention is greater than or equal to about 85%. 10. The multilayer structure of claim 1, wherein the adhesive layer comprises PVB. 11. A method for making a multilayered structure, comprising: disposing a initial terpolymer layer between a polycarbonate layer and an adhesive layer, wherein the initial terpolymer layer comprises a polycarbonate terpolymer derived from a first dihydroxy compound, a second dihydroxy compound, and a third dihydroxy compound, wherein the first dihydroxy compound has Structure (A) wherein Rf is a hydrogen or CH3; the second dihydroxy compound has Structure (A) and is different from the first dihydroxy compound; andthe third dihydroxy compound does not Structure (A), wherein a sum of mole percent of all of the first dihydroxy compound and the second dihydroxy compound is greater than or equal to 45% relative to a sum of mole percent of all of the first dihydroxy compound, the second dihydroxy compound, and the third dihydroxy compound in the polycarbonate terpolymer; anddisposing a second layer on a side of the adhesive layer opposite the initial terpolymer layer, wherein the second layer comprises plastic and/or glass; andwherein the adhesive layer comprises a material selected from the group consisting of PVB, EVA, and combinations comprising at least one of the foregoing. 12. The method of claim 11, wherein disposing the initial terpolymer layer between the polycarbonate layer and the adhesive layer further comprises solution casting the initial terpolymer layer on the polycarbonate layer. 13. The method of claim 11, wherein disposing the initial terpolymer layer between the polycarbonate layer and the adhesive layer further comprises co-extruding the initial terpolymer layer and the polycarbonate layer. 14. The method of claim 11, wherein the initial terpolymer layer comprises a polycarbonate formed from hydroquinone, methyl hydroquinone, and BPA, and wherein disposing the initial terpolymer layer between the polycarbonate layer and the adhesive layer further comprises co-extruding the adhesive layer between the initial terpolymer layer and an additional terpolymer layer. 15. The method of claim 11, wherein the initial terpolymer layer further comprises phosphoric acid or phosphorous acid. 16. The method of claim 15, wherein the initial terpolymer layer comprises about 5 ppm to about 15 ppm phosphoric acid or phosphorous acid. 17. The method of claim 16, wherein the initial terpolymer layer comprises about 8 ppm to about 12 ppm phosphoric acid or phosphorous acid. 18. The method of claim 15, wherein the initial terpolymer layer comprises a sufficient amount of the phosphoric acid or phosphorous acid to attain, in the multilayer structure, a flexed plate impact retention at maximum force of greater than or equal to about 65% after two weeks of exposure to 70° C. and 95% relative humidity. 19. The method of claim 11, wherein the adhesive layer comprises PVB.
