ABSTRACT:
This invention is a low cost styrene-soluble unsaturated polyester resin made using recycled or virgin polyethylene terephthalate. The PET is first glycolyzed using inexpensive glycols and then reacted with maleic anhydride and dicyclopentadiene, forming polyesters containing cyclopentadiene added by Diels-Alder reaction and/or norbornyl-terminated polyesters.
