HYPERBRANCHED POLYMER, ELECTRODE FOR FUEL CELL COMPRISING THE HYPERBRANCHED POLYMER, ELECTROLYTE MEMBRANE FOR FUEL CELL COMPRISING THE HYPERBRANCHED POLYMER, AND FUEL CELL USING AT LEAST ONE OF THE ELECTRODE AND THE ELECTROLYTE MEMBRANE

摘要

PURPOSE: A hyperbranched polymer with excellent heat resistance is provided to manufacture a fuel cell with improved lifetime property and cell properties. CONSTITUTION: A hyperbranched polymer is the product obtained through condensation polymerization of a composition for forming the hyperbranched polymer consisting of a diisocyanate-based compound represented by chemical formula 1 and a dihydroxy amine-based compound represented by chemical formula 2. In chemical formula 1, A is a substituted or unsubstituted C1-C30 alkylene group, substituted or unsubstituted C2-C30 alkenylene group, substituted or unsubstituted C2-C30 alkynylene group, substituted or unsubstituted C6-C30 arylene group, substituted or unsubstituted C2-C30 heteroarylene group, substituted or unsubstituted C4-C30 carbon ring group, or substituted or unsubstituted C6-C30 condensed polycyclic group.
