Abstract
A method for preparing a thermoplastic vulcanizate, the method comprising dynamically vulcanizing a rubber within a blend that includes the rubber and a thermoplastic polymer, where said dynamically vulcanizing is effected with a cure system that includes a hydrosilating agent and a catalyst, where the hydrosilating agent includes a compound including at least 3 silicon hydride groups defined by the formulawhere each R is independently a monovalent organic group or hydrogen, and where the silicon atoms of the respective silicon hydride groups are spatially separated by at least 6 atoms.
