Abstract
A composition includes a post-cured polymer. A post-cured polymer is formed from a polymer that is a reaction product of a polyfunctional cycloolefin and a metathesis catalyst. The post-cured polymer has a glass transition temperature in a range that is greater than 340 degrees Celsius. An associated article and a method are also provided.

A composition, comprising a post-cured polymer formed from a polymer that is a reaction product of:
- a polyfunctional cycloolefin comprising two or more metathesis-active double bonds;
- and
- a metathesis catalyst;
- wherein the post-cured polymer has a glass transition temperature in a range that is greater than 340 degrees Celsius.
A composition, comprising a post-cured polymer that results from:
- metathesis polymerization of a polyfunctional cycloolefin comprising two or more metathesis-active double bonds to form a polymer, and
- post-curing the polymer at a temperature that is greater than an onset temperature for secondary curing of the polymer.
A composition, comprising a post-cured polymer formed from a polymer that is a reaction product of:
- a polyfunctional cycloolefin comprising two or more metathesis-active double bonds;
- and
- a metathesis catalyst,
- wherein the post-cured polymer has a glass transition temperature that is greater than 340 degrees Celsius, and the post-cured polymer has an olefinic carbon content that is less than about 35 percent.
A method, comprising:
- initiating a metathesis polymerization of a polyfunctional cycloolefin comprising two or more metathesis-active double bonds;
- and
- post-curing the resulting polymer at a temperature that is greater than an onset temperature for secondary curing of the polymer.
