| titleOfInvention | Process for the production of high molecular weight polyester resins |
| abstract | PCT No. PCT/EP92/00670 Sec. 371 Date Dec. 28, 1992 Sec. 102(e) Date Dec. 28, 1992 PCT Filed Mar. 26, 1992 PCT Pub. No. WO92/17522 PCT Pub. Date Oct. 15, 1992.A process for the solid state upgrading of a polyester resin by polyaddition reaction in which the resin is upgraded in the presence of an upgrading additive which is a compound different from a dianhydride of an aromatic tetracarboxylic acid, containing two groups capable of addition reactions with the terminal groups of the polyester, selected for example in the group of the dianhydrides of aliphatic and cycloaliphatic tetracarboxylic acids. |
