| titleOfInvention | Method for producing polyhydroxycarboxylic acid copolymer resin |
| abstract | (57) [Abstract] [Problem] It can be used for agricultural and horticultural materials, fishery materials, binders, etc., and is hydrolyzed even if discarded after use, or carbon dioxide and water due to microorganisms in the soil. To provide a method for easily producing a polyhydroxycarboxylic acid copolymer resin that is decomposed into the like. SOLUTION: A polymerization catalyst such as 1,3-substituted-1,1,3,3-tetraorganodistannoxane is added to a mixture of hydroxycarboxylic acid such as L-lactic acid and metal oxide such as calcium hydroxide or phosphoric acid. Is added, and the mixture is heated and stirred under reduced pressure or in the presence of an organic solvent to obtain a copolymer resin. Or The hydroxycarboxylic acid to which the polymerization catalyst has been added is dehydrated or made into an oligomer, then a metal oxide is added, and the mixture is heated and stirred under reduced pressure or in the presence of an organic solvent to obtain a copolymer resin. |
