| titleOfInvention | Method for producing meltable polyesters |
| abstract | This invention relates to a method for producing and processing polyester block copolymers, in particular, polyester side-chain grafted, rigid side-chain and/or semi-rigid side-chain polymers. According to the invention, the monomeric units of rigid side-chain and/or semi-rigid side-chain polymers are, preferably in the melt, polycondensated together with monofunctionalized and/or difunctionalized, cyclic dicarboxylic acid anhydrides to form polymers having anhydride terminal and/or side groups. The formed polyester anhydrides are reacted with the hydroxyl groups and/or with the ester groups of meltable linear polyesters in order to form side-chain grafted, rigid side-chain and/or semi-rigid side-chained polymers and, together with meltable polyesters, they form molecularly reinforced blends. These blends can be shaped into filaments or fibers having a high orientation of the reinforcing polymer or they serve as compatibility mediators in blends consisting of a polyester matrix and of rigid side-chain and/or semi-rigid side-chain polymers. The filaments are used, in particular, in technical fields or in the carpet industry. |
