Process for the production of modified polyesters.

摘要

There is disclosed a process for producing polyesters and co-polyesters modified with certain polyoxyalkylene glycols using coordination complex catalysts of (I) a metal halide compound and certain silicon compounds or (II) a mixture of said coordination complex catalyst of said compounds with antimony diglycollate. There are also disclosed polyoxyalkylene glycol-modified polyesters produced by such process.
