<p>A cycloolefinic resin composition of the invention comprises a thermoplastic resin comprising an alicyclic olefin polymer and a specified stabilizer selected from among phenolic stabilizers, organic thioether stabilizers, organic phosphite stabilizers, ultraviolet absorbers and hindered amine stabilizers. Since this composition contains a specified stabilizer, it is excellent in thermal aging resistance and weatherability and can be preferably used as the resin composition for making an optical member. The thermoplastic resin may also be one comprising both of an alicyclic olefin polymer and a flexible polymer, whereby especially the mechanical strengths are improved and a resin composition containing said resin is preferably used in the manufacture of machine parts, electronics components and automotive parts.</p> |
