Polymers are disclosed that include a structure having the formula (I) wherein, R<SUP>1</SUP> is independently selected from a C<SUB>2-10</SUB> n-alkylene group, a C<SUB>2-6</SUB> branched alkylene group, a C<SUB>6-8</SUB> cycloalkylene group, a C<SUB>6-10</SUB> alkylcycloalkylene group, - [(-CH<SUB>2</SUB> - )<SUB>p</SUB>- X- ]<SUB>q</SUB> - (-CH<SUB>2</SUB> )<SUB>r</SUB> -, or - [(- CH<SUB>2</SUB>- )<SUB>p</SUB>-X-]<SUB>q</SUB>-(- CH<SUB>2</SUB> - )<SUB>r </SUB>-, wherein at least one - CH<SUB>2</SUB> - 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 <SUP> - NR - </SUP>, wherein R is hydrogen or methyl; R<SUP>2</SUP> denotes a structure derived from allyl (meth)acrylate or a multi-functional (meth)acrylate; R<SUP>3</SUP> 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. |
