IPC: C08G63/82
Filed: 1982-12-07
Abstract: PURPOSE:To obtain a polyester excellent in color, transparency, and thick-wall moldability, by polycondensing bis-(beta-hydroxyethyl) terepthalate in the presence of both a catalyst and specified compounds. CONSTITUTION:In producing a polyester by polycondensing bis-(beta-hydroxyethyl) terepthalate or a composition based on this by using an antimony compound as a catalyst; said polycondensation is performed in the presence of an organo- polyborosiloxane, an organotin compound, and diethylene glycol.
