シクロオレフィンコポリマーおよび熱可塑性ポリウレタンの透明な熱可塑性ブレンド

Title:

シクロオレフィンコポリマーおよび熱可塑性ポリウレタンの透明な熱可塑性ブレンド

Document Type and Number:

Japanese Patent JP2007506849

Kind Code:

A

Abstract:

A blend of a cycloolefin copolymer and a thermoplastic urethane having similar indices of refraction is transparent. The cycloolefin copolymer is derived from norbornene and other monomers such that it has a processing range compatible with the thermoplastic urethane. The urethane component preferably has a polyether intermediate. A thermoplastic urethane compatibilizing agent is utilized desirably having a hydrocarbon intermediate portion. The compositions can be made to have desirable electrical dissipative properties for static control applications.
