摘要： The invention relates to a process for making modified polybutylene terephththalate random copolymers from a polyethylene terephthalate component. The invention relates to a three step process in which a diol component selected from the group consisting of ethylene glycol, propylene glycol, and combinations thereof reacts with a polyethylene terephthalate component under conditions sufficient to depolymerize the polyethylene terephthalate component into a first molten mixture; and where the first molten mixture is combined with 1,4-butanediol under conditions that create a second molten mixture that is subsequently placed under subatmospheric conditions that produce the modified polybutylene terephthalate random copolymers. The invention also relates to compositions made from the process.

摘要： Methods for purifying a p,p-bisphenol A generally include distilling a feed stream comprising p,p-BPA in a distillation column at a pressure less than or equal to 20 millibars. The distillation column separates the bisphenol feed stream to produce a light fraction, an intermediate fraction and a heavy fraction. The intermediate fraction comprising the purified bisphenol contains lesser impurities that the p,p-BPA in the feed stream. In one embodiment, the intermediate stream is recovered using a side-draw. The side-draw is located between a first zone and a third zone in the distillation column.
摘要翻译：纯化p，p-双酚A的方法通常包括在压力小于或等于20毫巴的蒸馏塔中蒸馏包含p，p-BPA的进料流。蒸馏塔分离双酚进料流以产生轻馏分，中间馏分和重馏分。包含纯化双酚的中间馏分含有较少的杂质，即进料流中的p，p-BPA。在一个实施方案中，使用侧馏分回收中间物流。侧馏分位于蒸馏塔中的第一区和第三区之间。
