发明名称 Polythioether polymers and curable compositions containing them
摘要 <p>Polymers are disclosed that include a structure having the formula wherein, R 1 is independently selected from a C 2-10 n-alkylene group, a C 2-6 branched alkylene group, a C 6-8 cycloalkylene group, a C 6-10 alkylcycloalkylene group, -[(-CH 2 -) p -X-] q -(-CH 2 -) r -, or -[(-CH 2 -) p -X-] q -(-CH 2 -) r -, wherein at least one -CH 2 - unit is substituted with a methyl group, wherein p is an integer having a value ranging from 2 to 6, q is an integer having a value ranging from 1 to 5, r is an integer having a value ranging from 2 to 10, and X is selected from O, S, and -NR-, wherein R is hydrogen or methyl; R 2 denotes a structure derived from a multi-functional (meth)acrylate; R 3 is independently selected from hydrogen and an alkyl group; n is an integer having a value ranging from 1 to 60; and m is a rational number having a value ranging from 0 to 10. Also disclosed are curable compositions containing such polymers, methods for making such polymers, and methods of coating and/or sealing substrates with such compositions.</p>
