1. A method for preparing a vinylidene terminated polyolefin, comprising: (a) ionizing a polyolefin in the presence of a Lewis acid or mixture of Lewis acids to form an ionized polyolefin;(b) reacting the ionized polyolefin from step (a) with one or more disulfides of formula I to form an intermedia
1. A method for preparing a vinylidene terminated polyolefin, comprising: (a) ionizing a polyolefin in the presence of a Lewis acid or mixture of Lewis acids to form an ionized polyolefin;(b) reacting the ionized polyolefin from step (a) with one or more disulfides of formula I to form an intermediate; RA—S—S—RB Iwherein RA and RB are each independently alkyl, aryl, aralkyl, or alkaryl; and(c) reacting the intermediate of step (b) with one or more alcohols or amines. 2. The method of claim 1, wherein the vinylidene terminated polyolefin is a vinylidene terminated polyisobutylene. 3. The method of claim 1, wherein the intermediate of step (b) is reacted with one or more alcohols. 4. The method of claim 3, wherein the one or more alcohols are of the formula: R—OHwherein R is alkyl of 1-8 carbons. 5. The method of claim 3, wherein the one or more alcohols are one or more of methanol, ethanol, isopropanol, 2-ethylhexanol, and sec-butanol. 6. The method of claim 1, wherein RA and RB are the same. 7. The method of claim 1, wherein RA and RB are each independently alkyl. 8. The method of claim 7, wherein RA and RB are each independently methyl, ethyl, tert-butyl, or isopropyl. 9. The method of claim 7, wherein RA and RB are the same. 10. The method of claim 1, wherein RA and RB are each tert-butyl. 11. The method of claim 1, wherein the ionized polyolefin is a quasiliving carbocationic polyolefin and the method is performed under quasiliving carbocationic polymerization conditions. 12. The method of claim 11, wherein the quasiliving carbocationic polyolefin is prepared by adding a Lewis acid and a monomer to an initiator in the presence of an electron donor, common ion salt, or common ion salt precursor. 13. The method of claim 12, wherein the initiator is 2-chloro-2,4,4-trimethylpentane, 1,3-di(2-chloro-2-propyl)-5-tert-butylbenzene, or dicumyl chloride. 14. The method of claim 12, wherein the monomer is isobutylene or styrene. 15. The method of claim 12, wherein the electron donor is pyridine or a pyridine derivative. 16. The method of claim 15, wherein the electron donor is 2,6-dimethylpyridine, 2,4-dimethylpyridine, or 2,6-di-tert-butylpyridine. 17. The method of claim 12, wherein the common ion salt precursor is tetrabutylammonium chloride or tetrabutylammonium iodide. 18. The method of claim 1, wherein the Lewis acid is a titanium tetrahalide, a boron trihalide, an aluminum trihalide, a tin tetrahalide, zinc chloride, or ethyl aluminum dichloride, or a mixture thereof. 19. The method of claim 18, wherein the Lewis acid is titanium tetrachloride. 20. The method of claim 1, wherein a mixture of Lewis acids is used. 21. The method of claim 20, wherein the mixture of Lewis acids is a mixture of an aluminum (III) halide and a trialkyl aluminum. 22. The method of claim 20, wherein the mixture of Lewis acids is a mixture of an aluminum (III) halide and trimethyl aluminum. 23. The method of claim 1, wherein a diluent is used. 24. The method of claim 23, wherein the diluent is an alkane or alkyl halide, or a mixture thereof. 25. The method of claim 1, wherein the method is performed at a temperature from about −120° C. to about 0° C. 26. The method of claim 25, wherein the temperature is from about −70° C. to about −40° C. 27. The method of claim 1, wherein the Lewis acid or mixture of Lewis acids are present at a molar concentration of from about 0.5 to about 20 times chain-end molar concentration. 28. The method of claim 1, wherein the ionized polyolefin is formed by adding a Lewis acid to a tert-halide terminated polyolefin or adding a Lewis acid and a proton source to a preformed polyolefin.
