Patent ID: 8263709

Claim:
A polymer composition, comprising: a first polymer, comprising a first monomer unit derived from a monomer of Formula A: (R 1 SiO 1.5 ) x (R 2 SiO 1.5 ) y Formula A wherein R 1 is a polymerizable functional group, R 2 is a non-polymerizable group, and x is a positive integer and y is a positive integer, provided that x+y=2n, wherein n is an integer greater than or equal to 3; a second monomer unit copolymerizable with the first monomer unit; and a second polymer having no monomer units derived from a monomer of Formula A; wherein the content of the monomer unit of Formula A is 4 wt % or less, based on the total weight of the polymer components of the polymer composition, and wherein the content of the first polymer is from 0.1 to 3% by weight and the content of the second polymer is from 99.9 to 97% by weight.
