Stabilization of polymers that contain a hydrolyzable functionality

摘要

A process for treating a polymer having a hydrolyzable functionality, the process comprising:
(i.) providing a polymer having hydrolyzable functionality;(ii.) introducing an alkoxysilane to the polymer, where the alkoxysilane is defined by the formula I; where R2 is a hydrocarbyl group, R3, R4, and R5 are each independently a hydrocarbyl group or a hydrocarbyloxy group; and(iii.) introducing a silane having a hydrolyzable functionality, where the silane is defined by the formula II;
where χ is a hydrolyzable group that forms an acidic species upon hydrolysis, where R6, R7, and R8 are each independently a halogen atom, a hydrocarbyl group, a hydrocarboxylate group, or a hydrocarbyloxy group.

1. A process for treating a polymer having a hydrolyzable functionality, the process comprising:
(i) providing a polymer having hydrolyzable functionality; (ii) introducing a hydrocarbyl trihydrocarbyloxy silane to the polymer; and (iii) introducing a silane having a hydrolyzable functionality after said step of introducing the hydrocarbyl trihydrocarbyloxy silane, where the silane having a hydrolyzable functionality is defined by the formula II  where χ is a halogen atom, and where R6, R7, and R8 are each independently a halogen atom, a hydrocarbyl group, a hydrocarboxylate group, or a hydrocarbyloxy group.
