FILM COMPRISING CYCLIC OLEFIN (CO)POLYMER, FILM COMPRISING CYCLIC OLEFIN (CO)POLYMER COMPOSITION AND CROSS-LINKED FILM OF CYCLIC OLEFIN (CO)POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a cross-linkable cyclic olefin (co)polymer film retaining high optical transparency, storage stability, and heat resistance and giving excellent chemical resistant and solvent resistance and provide a film comprising the composition and its cross-linked film.;SOLUTION: This invention relates to a film that includes at least one of structural unit originating from an oxetane skeleton-having cyclic olefin, has a number-average molecular weight of 5,000 to 1,500,000 in the polystyrene conversion, and a film comprising the cyclic (co)polymer and a ring-opening reaction initiator for the oxetanyl group, and a cross-linked film obtained by cross-linking the film made of the (co)polymer composition.;COPYRIGHT: (C)2007,JPO&INPIT
