Abstract
Partially crosslinked thermoplastic polyesters of recurring linear moieties of the formula ##SPC1## Are described wherein n is 0 or 1, and p, q and r are integers which total 30 to 600. The polyester is partially crosslinked by oxidizing meltable polymer to a 'gelled' thermoplastic state, producing molecules of average molecular weights in the range of 10,000 to 1,000,000, preferably of 100,000 to 500,000.
