Optimum dipropylene glycol content polytrimethylene terephthalate compositions |
摘要 |
According to the invention, a polytrimethylene terephthalate is provided having 0.6 to less than 2 mole percent dipropylene glycol. Such compositions have a reduced tendency to generate acrolein when heated in air. These PTT polymer compositions exhibit improved and enhanced dyeability as compared to conventional PTT made by the DMT process and the TPA polycondensation/solid state polymerization processes.
