Patent number: 8906999Abstract: A thermosetting unsaturated polyester resin (UPR) composition comprising an unsaturated polyester polymer having at least two strained cycloolefinic double bonds and optional unstrained cycloolefinic double bonds, which can be cross-linked through a ring-opening metathesis polymerization (ROMP) or combination of ROMP and cationic or free radical polymerization is provided. No styrene is used in the resin composition. The thermosetting unsaturated polyester resin composition also comprises a catalyst system for the ring-opening metathesis polymerization, and in embodiments, can further comprise one or more optional unsubstituted or substituted cycloolefin monomer containing unsaturation, an optional co-catalyst selected from a cationic initiator or free radical initiator, and optional additives. The cured resin properties can be controlled through adjusting the structure and properties of the unsaturated polyester resin.Type: GrantFiled: February 15, 2012Date of Patent: December 9, 2014Assignee: CCP Composites US LLCInventors: Chih-Pin Hsu, Ming Yang Zhao, Steven L.

Publication number: 20140128511Abstract: The invention relates to thermosetting compositions containing isocyanurate ring(s) prepared through chain extension of an epoxy resin (a) with carboxyl-functional oligomers (b), which are the reaction product of polyols (i) containing one or more isocyanurate ring(s) and polycarboxylic acids or their anhydrides (ii). The polyols (i) containing one or more isocyanurate ring(s) can be prepared from the reactions of tris (2-hydroxyalkyl) isocyanurates with a modifier from a caprolactone or alkylene oxide, or glycidyl ester or glycidyl ether and mixtures thereof. The epoxy-functional thermosetting compositions containing an isocyanurate ring(s) can be further reacted with unsaturated acids, preferably (meth)acrylic acid, to obtain a curable polyacrylate. Both epoxy-functional isocyanurate and acrylate-functional isocyanurate thermosetting compositions can be further modified with a polyisocyanate to produce a composition that is useful as a reactive adhesive, binder or in other applications.Type: ApplicationFiled: January 10, 2014Publication date: May 8, 2014Applicant: CCP Composites US LLCInventors: Ming Yang Zhao, Chih-Pin Hsu
