Abstract:
1. An ethylenically unsaturated macromonomer comprising a random or block copolymer of Formula I: where L is a linear, branched, or cyclic hydrocarbyl chain, optionally containing heteroatoms or carbonyl Z is an ethylenically unsaturated free radical polymerizable group y is ≧2 x is ≧200 and wherein the ethylenically unsaturated groups are provided by a moiety selected from the group consisting of (meth)acrylamide, (meth)acrylate and styrenic moieties wherein x is at least 100 times greater than y; and after polymerization to form a polymer, the polymer has an E modulus in the range of 0.01-100 kPa.
