Abstract
A polymer composition, including: a first copolymer, including a first monomer unit derived from a monomer of Formula A:(R1SiO1.5)x(R2SiO1.5)y Formula Awherein R1 is a polymerizable functional group, R2 is a non-polymerizable group, 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.
