Process for the production of high molecular weight polyester resins |
| abstract |
A method of polyaddition in the solid state of a polyester resin is described in which the resin, mixed in the molten state with a dianhydride of an aromatic tetracarboxylic acid, is subjected to granulation and crystallization, after which it is valued. The process is characterized in that the crystallization and recovery temperature is between the glass transformation temperature and 170 ° C, preferably between 130 ° and 170 ° C. |
