METHOD FOR PRODUCING POLYHYDROXYURETHANE AND AQUEOUS DISPERSION OF POLYHYDROXYURETHANE

PROBLEM TO BE SOLVED: To provide a method for producing a polyhydroxyurethane by which water resistance is good and an optional hydroxyl value can be selected. SOLUTION: The polyhydroxyurethane is produced. In the process, a mixture of an amidodiamine monomer represented by general formula (1) (wher...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a polyhydroxyurethane by which water resistance is good and an optional hydroxyl value can be selected. SOLUTION: The polyhydroxyurethane is produced. In the process, a mixture of an amidodiamine monomer represented by general formula (1) (wherein, n is an integer of ≥1; R represents a 2-12C alkylene, a cycloalkylene or a phenylene: and R1represents a 2-10C alkylene, a cycloalkylene or a phenylene) with a carbonate monomer having at least two 5-membered cyclic carbonate groups in one molecule is reacted and converted into a high molecular weight.
