POLYCYCLO-OLEFINIC BLOCK COPOLYMERS

摘要

A series of vinyl addition block polymers derived from functionalized norbornene monomers are disclosed and claimed. Specifically, a series of diblock and triblock polymers derived from norbornene monomers are disclosed. Also disclosed are the method of preparation of such block polymers, and their use in the fabrication of membranes which exhibit unique separation properties.
