摘要
The invention relates to a process for preparing branched polyester polyols to be used in preparation of alkyd-type polymeric resins. According to the invention, the process consists in solvolysis of polyethylene terephthalate wastes with monoacylpolyol synthesized by alcoholysis of animal fats, in the presence of a polyol, in a reactor heated by microwaves with a frequency of 2.45 GHz, at a microwave density of 10...600 W/kg.
