AMORPHOUS POLYESTER RESIN COMPOSITION

摘要

A substantially amorphous polyester resin composition which comprises 1 to 4 0 parts by weight of a core-shell impact resistance improving agent having, as a core, a bilayer aromatic vinyl-butadiene based copolymer having a refractive index of 1.55 to 1.60 and containing an innermost layer having a high conten t in weight of a monomer of cross-linking property, and 60 to 99 parts by weig ht of at least one aromatic polyester or co-polyester. The polyester resin composition exhibits high transparency and high impact resistance and is improved in the whitening at a low stress.
