CYCLIC OLEFIN-BASED RESIN CAPABLE OF FORMING A HIGH HEAT-RESISTANT FILM WITH IMPROVED COEFFICIENT OF THERMAL EXPANSION, HIGH TRANSMITTANCE, THERMAL STABILITY, AND THERMOGRAVIMETRIC ANALYSIS

摘要

PURPOSE: A cyclic-olefin-based resin is provided to improve a cross linked degree, and to remarkably improved physical properties including thermal expansion coefficient.;CONSTITUTION: A cyclic olefin-based resin comprises polynorbornene in chemical formula 1, and polysilsesquioxane in chemical formula 2. In chemical formula 1, R is selected from a substituted or unsubstituted C1-10 hydrocarbon group, a substituted or unsubstituted polar group, a substituted or unsubstituted aromatic group, a substituted or unsubstituted silane, and a substituted or unsubstituted halogen atom, n is an integer from 5,000-500,000. In chemical formula 2, X is one or more selected from a phenyl group, a vinyl group, an aryl group, and an acryl group, and n is an integer from 1-100,000.;COPYRIGHT KIPO 2013
