Abstract
A composition includes a post-cured polymer. A post-cured polymer includes a reaction product of a first cycloolefin and a metathesis catalyst having ruthenium, osmium, or both ruthenium and osmium. 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.
Claims25
A composition, comprising:
- a post-cured polymer formed from a polymer that is reaction product of:
- a first cycloolefin;
- and
- a metathesis catalyst comprising ruthenium, osmium, or both ruthenium and osmium,
- 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 a metathesis polymerization of a first cycloolefin initiated by a metathesis catalyst to form a polymer, and a post-curing of the polymer at a temperature that is greater than an onset temperature for a secondary curing reaction of the polymer.
A composition, comprising a post-cured polymer formed from a polymer that is a reaction product of:
- a first cycloolefin;
- 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 first cycloolefin by a metathesis catalyst to form a polymer;
- and
- post-curing the polymer at a temperature that is greater than an onset temperature for a secondary curing of the polymer.
