MULTICYCLIC OLEFIN POLYMER HAVING NORBORNENE MONOMER OF PAUSON-KHAND TYPE AND PREPARATION THEREOF

摘要

PURPOSE: Provided is a cyclic olefin addition polymer having a norbornene derivative obtained by Pauson-Khand reaction, which has low hygroscopic property, high glass transition temperature, excellent heat stability, oxidation stability, chemical resistance, metal adhesion and barrier property. CONSTITUTION: The polymer is a cyclic olefin addition homopolymer of the compound represented by the formula 1 or formula 2, wherein k is an integer of 0 to 4; each of l is independently or simultaneously an integer of 0 to 4; each of R1-R4 is independently or simultaneously hydrogen, halogen, a C1-C20 linear or branched alkyl, alkoxy, alkoxyalkyl, alkoxysilyl, alkylperoxy, alkylcarbonyloxy, aryloxy, aryloxysilyl, alkenyl or vinyl, a C6-C40 aryl substituted or non-substituted by a hydrocarbon, a C7-C15 aralkyl substituted or non-substituted by a hydrocarbon, a C3-C20 alkynyl or a sulfur-containing radical, in which R1 and R2, or R3 and R4, respectively, are bonded together to form a C1-C10 alkylidene group, a C3-C12 saturated or unsaturated cyclic group or a C6-C17 aromatic ring compound, if each of them is not hydrogen or a halogen; and R5 is an alkyl diradical, aryl diradical, alkoxyalkyl diradical, alkoxysilyl diradical or an alkenyl diradical.
