Claims34
A reactive polymer prepared by a method comprising:
- combining and copolymerizing monomers comprising N-isopropylacrylamide and a hydroxy-functional (meth)acrylate monomer to form a hydroxy-functional polymer;
- and
- reacting the hydroxy-functional polymer with a hydroxy-reactive material selected from the group consisting of a (meth)acrylate-functional isocyanate, a (meth)acrylate-functional epoxide, a vinyl azlactone, and combinations thereof,
- wherein the reactive polymer comprises a non-terminal monomeric unit comprising a pendant ethylenically unsaturated group and copolymerized N-isopropylacrylamide.
