Abstract:
1. An addition-fragmentation agent comprising: 1) a labile addition-fragmentation group, 2) a free-radically polymerizable group, and 3) a surface-modifying functional group that associates with the surface of a substrate, said addition-fragmentation agent of the formula: wherein R Q is a covalent bond or a linking group, having a valence of m+1; Q′ is a covalent bond or a linking group, having a valence of p+1; Z is an ethylenically unsaturated polymerizable group (meth)acryloxy, (meth)acrylamido, and styrenic groups, Y is a functional group that bonds with a substrate on which the addition-fragmentation agent is disposed; m is 1 to 6; p is 1 or 2; each X n is 0 or 1.
