Abstract
There is provided a curable composition comprising (A) a cyclic olefin; (B) a metathesis catalyst for polymerizing the cyclic olefin; (C) 0.1-30 wt. % of a compound comprising at least one vinyl group; and (D) 0.1-10 wt. % of a curing agent for compound (C), wherein the wt. % are relative to the total weight of the composition. The composition provides a desirable combination of workability, toughness and heat resistance. Also provided is a molded article comprising the composition and reinforcing fibers, and a method of manufacturing the same.
Claims20
A method of manufacturing a molded article of a curable composition, the method comprising:
- combining at least the following components:
- (A) a cyclic olefin;
- (B) a metathesis catalyst for polymerizing the cyclic olefin;
- (C) 0.1-30 wt. % of a compound comprising at least one vinyl group;
- and
- (D) 0.1-10 wt. % of a curing agent for compound (C),
- wherein the wt. % are relative to the total weight of the composition to form the composition;
- and
- subjecting the composition to conditions effective to promote an olefin metathesis reaction of the cyclic olefin and a radical polymerization of compound (C).
