摘要：
An article includes a crosslinked product of: a first crosslinked polymer and a second crosslinked polymer, wherein the article has a gradient in glass transition temperature. A process for making the article includes combining a first crosslinked polymer and a second crosslinked polymer to form a composition; compressing the composition; heating the composition; and crosslinking the composition to form the article, the article having a gradient in glass transition temperature. An article can be a seal that includes a first portion including a crosslinked product of: a first crosslinked polymer and a second crosslinked polymer; and a second portion including a polymer which is different than a constituent polymer in the first portion, wherein the seal has a gradient in glass transition temperature.
