1. A polymer material, formed by polymerizing a liquid monomer mixture comprising:
a macromonomer (A) represented by the following formula (I); and
a (meth)acrylate monomer (B) with an aryl group, and
optionally a (meth)acrylate monomer (C) without having an aryl group, or a cross-linking monomer (D), or both the monomers (C) and (D),
wherein an amount of the macromonomer (A) is in a range from 11 to 30% relative to a total mass of the macromonomer (A), the (meth)acrylate monomer (B), the (meth)acrylate monomer (C) when present, and the cross-linking monomer (D) when present, in the liquid monomer mixture,
