METHOD OF PRODUCING HYPER-BRANCHED POLYMER COMPRISING OXETANE COMPOUND AND POLYFUNCTIONAL CARBOXYLIC ACID COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a new production process of a hyper-branched polymer having excellent characteristics not seen in a linear polymer. SOLUTION: This method of producing a hyper-branched polymer is a polyaddition reaction of an oxetane compound with a polyfunctional carboxylic acid having three or more functional groups in a molecules.
