Abstract
The present invention provides network polymers obtained by curing compositions that comprise an ester with at least two terminal epoxy groups. Preferred esters include those represented by the formula (1), wherein each R1 independently represents a substituted or unsubstituted homoaliphatic or heteroaliphatic group; A represents a substituted or unsubstituted homoalkylene, hetemalkylene, arylene, or heteroarylene segment; and n represents an integer equal to or greater than 2.
Claims18
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.
A curable composition comprising
- 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.
