Abstract
A method of preparing functionalized elastomers, including epoxy ring-opening an epoxidized elastomer with a C1-C32 hydrocarbyl-substituted thiol to provide a functionalized elastomer comprising an epoxy functional group, a hydroxy functional group, and a C1-C32 hydrocarbyl-substituted thio functional group. The hydroxy functional group and the C1-C32 hydrocarbyl-substituted thio functional group are vicinal functional groups.
Claims20
A method of preparing a functionalized elastomer, the method comprising:
- providing an epoxidized elastomer;
- epoxy ring-opening of the epoxidized elastomer with a C1-C32 hydrocarbyl-substituted thiol to provide a functionalized elastomer comprising:
- an epoxy functional group,
- a hydroxy functional group, and
- a substituted or unsubstituted C1-C32 hydrocarbyl-substituted thio functional group, wherein the hydroxy functional group and the substituted or unsubstituted C1-C32 hydrocarbyl-substituted thio functional group are vicinal functional groups.
