Patent ID: 7247684

Claim:
A network polymer resulting from curing a composition comprising (I) An epoxy-terminated ester selected from the group consisting of 10,11-epoxyundecenoyl triglyceride, 9,10-epoxydecenoyl triglyceride, and 4,5-epoxypentenoyl triglyceride; the composition comprising at least 40 wt. % of said epoxy-terminated ester, relative to the total weight of epoxy-functional components present in the composition; (II) optionally, one or more further epoxy-functional component(s) other than the epoxy-terminated ester (I); and (III) a curing component selected from the group consisting of: (A) one or more aliphatic amine curing agents with an accelerator; (B) one or more non-aliphatic-amine curing agents with a polymerization catalyst, the non-aliphatic-amine curing agent or agents being selected from the group consisting of aromatic amines, isocyanates, bisphenols, polyfunctional acids, imidazoles, polyfunctional mercaptans, boron trihalide complexes, dicyanamides, and mixtures thereof; and (C) one or more iodonium salt or sulfonium salt curing agents optionally with a polymerization catalyst and optionally with a photosensitizer.
