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.

Patent number: 8288453Abstract: A process to disperse organic microparticles/nanoparticles into non-aqueous resin medium is provided. The process includes the steps of a) preparing a resin dispersion/emulsion in water and/or solvent where the resin contains unsaturation in the polymer chain and optionally comprises an ethylenically unsaturated monomer; b) curing the resin dispersion/emulsion by adding monomer and/or initiator; and c) adding the cured dispersion/emulsion during a synthesis step of a resin medium. The amount of organic microparticles/nanoparticles in the resin medium can be about 2 to about 30% by weight based on the total weight of the composition.Type: GrantFiled: May 28, 2009Date of Patent: October 16, 2012Assignee: CCP Composites USInventors: Chih-Pin Hsu, Ming Yang Zhao, Steven L.
