摘要： Disclosed is a method for depolymerization of polyester. The method includes (a) treating said polyester with methanol under conditions sufficient to depolymerize at least some of said polyester and form a reaction product that includes dimethyl terephthalate and at least one diol; and (b) converting the diol to a compound substantially non-reactive with said with dimethyl terephthalate and the polyester. A method for producing a cyclic carbonate is also described.

摘要： This invention relates to a process for making a polycondensation pre-polyester, a polyester or both, comprising the following steps: A. Acylation of at least one diacid chloride with at least one alcohol to form at least one diester; B. Partial hydrolysis of the diester product of Step A to form at least one monoacid; C. Esterifying the monoacid of Step B with at least one diol to form a diester; D. Reacting the diester of Step C under acidic conditions to form a diacid; and subsequently, performing either Step E or Step F as follows: E. Bisalkylation of the diacid of Step D with at least one haloalcohol to form a pentamer, or F. Esterifiying the diacid of Step D under esterification conditions with at least one diol to form a pentamer, provided that the diol is not the same as the diol used in Step C.
