Abstract:
An object of this invention is to provide an ablative, high-temperature silphenylene-vinylmethylsiloxane elastomer having good thermal stability as well as good mechanical properties. Another object of this invention is a process for producing a high temperature, high impact, erosion resistant silphenylene-vinylmethylsiloxane elastomer. This patent describes a high temperature, high impact, erosion resistant silphenylene-vinylmethylsiloxane elastomer and a process for making the same in which a liquid hydroxyl-terminated silphenylene vinylmethylsiloxane polymer is cured using a combination of hydrosilylation cure and urethane cure techniques.
