Polymers are disclosed that include a structure having the formula (I) wherein, R1 is independently selected from a C2-10 n-alkylene group, a C2-6 branched alkylene group, a C6-8 cycloalkylene group, a C6-10 alkylcycloalkylene group,-[(-CH2-)p-X-]q-(-CH2)r-, or-[(-CH2-)p-X-]q-(-CH2-)r -, wherein at least one-CH2-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; R2 denotes a structure derived from allyl (meth)acrylate or a multi-functional (meth)acrylate; R3 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. ® KIPO & WIPO 2008
