<p>The present invention relates to addition copolymers of cyclic olefins, and in particular, cyclic olefin copolymers of norbornene type compounds containing sulfur to provide excellent adhesiveness to metal, and methods for using the same. Therefore, the present invention provides addition copolymers of cyclic olefins of norbornene type compounds and norbornene type compounds containing sulfur, and methods for preparing the same. The copolymers of norbornene type compounds containing sulfur of the invention are addition copolymers of cyclic olefins, which are very useful for dielectric materials because of their low dielectric constant, excellent thermal stability, strength, and good adhesiveness to metals without generating any by-products while adhering to metal.</p> |
