Patent

CA 2255590

This invention discloses blends of cyclic olefin polymers and styrene- containing elastomers useful as molding compositions to mold articles thereform. The articles so molded exhibit improved mechanical properties without any significant effect on optical properties, making them ideally suitable for applications such as optical discs, lenses and the like.

L'invention concerne des mélanges de polymères d'oléfine cyclique et d'élastomères contenant un styrène utiles en tant que compositions de moulage pour mouler des articles à partir de ces compositions. Les articles ainsi moulés présentent de meilleures propriétés mécaniques sans affecter de manière significative leurs propriétés optiques, les rendant ainsi particulièrement appropriées à des applications telles que disques optiques, lentilles et autres.
