| titleOfInvention | Production of copolyester |
| abstract | PURPOSE: To obtain the titled high-quality polymer by controlling foaming during reaction, by transesterifying a dicarboxylic acid component with a glycol component in the presence of three specified compounds and adding polyethylene glycol to the reaction system and polycondensing the whole. n CONSTITUTION: An aromatic dicarboxylic acid component based on dimethyl terephthalate and a glycol component based on ethylene glycol are mixed with 1.3W2.5mol% of 5-sodiosulfoisophthalic acid (derivative) of formula I (wherein M is Na, Li or K, A and A' are each a lower alkyl or formula II and n≥2), 0.01W2wt% antioxidant of a hindered phenol type (e.g., formula III) and 0.001W0.5wt% silicon compound of formula IV (wherein R is a 1W20C alkyl or allyl and n is a degree of polymerization) and having a viscosity at 25°C of 10W10,000cSt and transesterified with each other. 0.5W3wt% polyethylene glycol of a MW of 300W4,000 is added to the reaction mixture and the whole is polycondensed to obtain a copolyester. n COPYRIGHT: (C)1986,JPO&Japio |
