| titleOfInvention | Process for producing polyetherester block copolymer |
| abstract | PROBLEM TO BE SOLVED: To provide a method for efficiently producing a polyetherester block copolymer having a low concentration of terminal COOH groups in a produced copolymer, good thermal stability and hydrolysis resistance, and little cloudiness. SOLUTION: (a) Lower alkyl ester of aromatic dicarboxylic acid and / or lower alkyl ester of alicyclic dicarboxylic acid, (b) aliphatic glycol and / or alicyclic glycol, (c) polyalkylene ether glycol In producing a polyetherester block copolymer by carrying out a transesterification reaction and a subsequent polycondensation reaction using a titanium compound and a magnesium compound as catalysts, (d) the organic carboxylic acid is within a range satisfying the following formula (1): A method for producing a polyetherester block copolymer, which comprises adding a polyetherester block copolymer. ([D] indicates the mole fraction of the component (d), and [a] indicates the mole fraction of the component (a).) [Selection figure] None |
