Patent ID: 7408013

Claim:
A low polydispersity copolymer comprising: a. a repeat unit derived from an acrylic monomer selected from the group consisting of MAdA, HAdA, PinAc, PinMAc, and CH 2 ═C(CH 2 OH)CO 2 R′″, wherein R′″ is a C 1 -C 25 alkyl group, optionally substituted by one or more hydroxy, halogen, ether oxygen, ester or ketone carbonyl groups; b. a repeat unit derived from an unsaturated polycyclic monomer; and c. a functional group selected from the group of fluoroalcohol, protected fluoroalcohol and protected acid group; wherein at least 40 mole % of the repeat units of the low polydispersity copolymer are derived from acrylic monomers and the polydispersity is 1.05-2.0.
