Process for the manufacture of polybutylene terephthalate copolymers from polyethylene terephthalate and compostions and articles thereof

摘要

The method comprises reacting a first polymer comprising polyethylene terephthalate with at least one second polymer selected from the group consisting of polyvinyl chloride, polyvinylidene chloride, polyamide, polylactic acid, - / RTI butanediol to prepare a molten mixture; And polymerizing the molten mixture under conditions sufficient to form a modified polybutylene terephthalate copolymer. Wherein the modified PBT comprises (a) at least one polyethylene terephthalate component residue, and (b) at least one selected from the group consisting of (i) polyvinyl chloride, polyvinylidene chloride, polyamide, poly lactic acid, One second polymer; (ii) said at least one residue derived from said second polymer; And combinations thereof.
