Patent ID: 8163815

Claim:
A curable (meth)acrylate resin for dental compositions, comprising: a compound according to Structure IIIa wherein M is selected from the group consisting of phenyl, C 1 -C 3 alkylphenyl, and C 5 -C 14 alkylene; G is an aromatic hydrocarbyl group; X 1 is O or —NR 1 ; Q is substituted or unsubstituted C 1 -C 16 alkylene, arylene, —C 1 -C 4 alkyl-aryl-C 1 -C 4 alkyl-, or polyether, wherein when Q is substituted, the substituents are selected from the group consisting of cyano, hydroxyl, nitro, azido, alkanoyl, carboxamido, alkyl, alkoxy, aryloxy, alkylthio, alkylsulfinyl, alkylsulfonyl, aminoalkyl, aryl, alkylaryl, arylalkoxy, aromatic heterocyclic, and combinations thereof; R 1 is hydrogen, a substituted or unsubstituted alkyl, alkenyl, aryl, or -alkylaryl group, wherein when R 1 is substituted, substituents are selected from the group consisting of alkyl, aryl, alkylaryl, arylalkoxy, and aromatic heterocyclic; R 2 is H or methyl; each instance of R 3 is independently hydrogen or C 1 -C 12 alkyl; x is 1 or 2; q is 0 or 1; n 1 is 2; and n 2 is 1 or 2; wherein the curable (meth)acrylate resin is free of units derived from bisphenol A or bisphenol A analogs; and wherein the curable (meth)acrylate resin is a reaction product obtained by i) reacting an anhydride with an alcohol M(OH) p or an amine M(NR 1 H) p , wherein p=1, 2, 3, 4, 5 or 6 to obtain a carboxy ester or a carboxy amide, and ii) reacting the carboxy ester or carboxy amide with a (meth)acrylate monomer comprising an epoxide group or an oxetane group to obtain a curable (meth)acrylate resin for dental compositions.
