대표청구항▼
1. A foamable composition comprising: (a) a foam forming agent comprising: (i) at least one thermoplastic for forming a thermal insulating foam, said thermoplastic consisting essentially of at least one polystyrene; and (ii) a blowing agent consisting essentially of 1,1,1,3-tetrafluoropropene (HFO-1
1. A foamable composition comprising: (a) a foam forming agent comprising: (i) at least one thermoplastic for forming a thermal insulating foam, said thermoplastic consisting essentially of at least one polystyrene; and (ii) a blowing agent consisting essentially of 1,1,1,3-tetrafluoropropene (HFO-1234ze) and at least one co-blowing agent that is not HFO-1234ze, wherein said blowing agent comprises at least about 50% by weight of 1,1,1,3-tetrafluoropropene (HFO-1234ze), wherein said HFO-1234ze consists of trans-1,1,1,3-tetrafluoropropene (transHFO-1234ze), provided that said blowing agent of (ii) is the sole blowing agent in said foam forming agent. 2. The foamable composition of claim 1 wherein said co-blowing agent comprises at least one compound selected from the group consisting of C4-C6 hydrocarbons, C1-C5 alcohols, C1-C4 ethers, and combinations of two or more of these. 3. The foamable composition of claim 1 wherein said co-blowing agent comprises ethanol. 4. The foamable composition of claim 1 wherein said co-blowing agent comprises a compound selected from the group consisting of dimethyl ether, diethyl ether and combinations of these. 5. A method of forming a foam comprising adding to a foamable and/or foaming composition comprising thermoplastic polymer consisting essentially of at least one polystyrene capable of forming a thermal insulating foam a blowing agent consisting essentially of 1,1,1,3-tetrafluoropropene (HFO-1234ze) and at least one co-blowing agent that is not HFO-1234ze, wherein said blowing agent comprises at least about 50% by weight of 1,1,1,3-tetrafluoropropene (HFO-1234ze), and wherein said HFO-1234ze consists of trans-1,1,1,3-tetrafluoropropene (transHFO-1234ze), provided that said blowing agent of (ii) is the sole blowing agent in said foam forming agent. 6. The method of claim 5 further processing the foamable composition under conditions effective to form a substantially closed-cell cellular structure. 7. The method of claim 5 wherein said foamable composition comprises at least one additional component selected from the group consisting of catalysts, surfactants, flame retardants, colorants, and combinations of these. 8. A thermal insulating foam consisting essentially of at least one polystyrene having a plurality of closed cells in said at least one polystyrene and a composition contained in a plurality of said cells, said composition comprising at least a blowing agent comprising a blowing agent consisting essentially of 1,1,1,3-tetrafluoropropene (HFO-1234ze) and at least one co-blowing agent that is not HFO-1234ze, wherein said blowing agent comprises about 50% by weight of 1,1,1,3-tetrafluoropropene (HFO-1234ze), and wherein said HFO-1234ze consists of trans-1,1,1,3-tetrafluoropropene (transHFO-1234ze), provided that said blowing agent of (ii) is the sole blowing agent in said foam forming agent. 9. An article selected from the group consisting of block, foam, and laminate comprising the foam of claim 8. 10. The foam of claim 8 being in a form selected from the group consisting of rigid foam, one component foam, froths and integral skin foam. 11. A refrigerator comprising the foam of claim 8. 12. A freezer comprising the foam of claim 8. 13. The foam of claim 8 having a k-factor K-factor (BTU in / hr ft2 ° F.) at 40° F. of not greater than about 0.14. 14. The foam of claim 8 having a k-factor K-factor (BTU in / hr ft2 ° F.) at 75° F. of not greater than about 0.16. 15. The foamable composition of claim 1 wherein said co-blowing agent comprises 1,1,1,2-tetrafluoroethane (HFC-134a). 16. The method of claim 5 wherein at least a portion of said blowing agent is added to the foamable composition by third stream addition. 17. The method of claim 5 wherein said blowing agent is added at the foam head. 18. The method of claim 5 wherein said blowing agent further comprises at least one additional component and wherein said one additional component is added to the foamable composition and/or the foam at a location different than said trans-1,1,1,3-tetrafluoropropene (transHFO-1234ze). 19. The method of claim 5 further comprising extruding the foamable composition in extrusion equipment and wherein said adding step comprises introducing some or all of the blowing agent into the extrusion equipment at a location different than the location at which the foamable composition is introduced into the extrusion equipment. 20. The foamable composition of claim 1 wherein said co-blowing agent comprises HFCO-1233zd. 21. The foamable composition of claim 20 wherein said co-blowing agent comprises CO2. 22. The foamable composition of claim 21 wherein said CO2 is present in the blowing agent in an amount of from about 20% to about 50% by weight of the blowing agent. 23. The foamable composition of claim 20 wherein said co-blowing agent comprises dimethyl ether. 24. The foamable composition of claim 20 wherein said co-blowing agent comprises C4 hydrocarbon. 25. The foamable composition of claim 20 wherein said co-blowing agent comprises butane. 26. The foamable composition of claim 25 wherein said butane comprises isobutane. 27.
