Abstract
Abstract Dental restorative, pit and fissure sealant compositions having improved environmental resistance include a brominated acrylate such as dibromopropyl methacrylate and/or a diacrylate of the formula: ##STR1## where n is an integer from 1 to 6, R 1 is hydrogen or alkyl of 1 to 6 carbon atoms, R 2 is alkylene of 1 to 5 carbon atoms or ##STR2## WHERE R 3 is hydrogen, alkyl of 1 to 4 carbon atoms or --OH and x and y are selected from 0 or an integer from 1 to 4 and Ar is a cyclic group, preferably an aromatic group.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
An ambient curing composition comprising a solution of a brominated diacrylate compound selected from compounds of the formula: ##STR8## where n is an integer from 1 to 6, R 1 is hydrogen or alkyl of 1 to 6 carbon atoms, R 2 is alkylene of 1 to 5 carbon atoms or ##STR9## where R 3 is hydrogen, alkyl of 1 to 4 carbon atoms or --OH and x and y are selected from 0 or an integer from 1 to 4 and Ar is an aromatic group; and a reactive diluent selected from the group consisting of monoacrylates, diacrylates and triacrylates.
Claim 2
Dependent Claim
101 words
An ambient curing composition comprising a solution of a brominated diacrylate compound selected from compounds of the formula: ##STR8## where n is an integer from 1 to 6, R 1 is hydrogen or alkyl of 1 to 6 carbon atoms, R 2 is alkylene of 1 to 5 carbon atoms or ##STR9## where R 3 is hydrogen, alkyl of 1 to 4 carbon atoms or --OH and x and y are selected from 0 or an integer from 1 to 4 and Ar is an aromatic group; and a reactive diluent selected from the group consisting of monoacrylates, diacrylates and triacrylates.
Claim 3
Dependent Claim
