OPTICAL COMPONENT COMPRISING ACRYLIC BLOCK COPOLYMER

摘要

It is an object of the invention to provide an optical component which comprises a material containing an acrylic block copolymer and having excellent melt processability and which is excellent in flexibility, light resistance and transparency. The optical component of the invention is formed from a composition containing an acrylic block copolymer having two or more polymer blocks (A) each of which is synthesized from monomers containing at least one monomer selected from methacrylic esters and acrylic esters and has a glass transition temperature of not lower than 50°C and one or more polymer blocks (B) each of which is synthesized from monomers containing at least one monomer selected from methacrylic esters and acrylic esters and has a glass transition temperature of not higher than 20°C.
