| titleOfInvention | Improved process for the preparation of block copolymers and block copolymers prepared therefrom |
| abstract | The present invention relates to a method for preparing a block copolymer, and to a block copolymer prepared therefrom, the block copolymer all comprising at least two homoblocks belonging to the polysulfone group, each said homoblock being at least 1000 identical Or having a different molecular weight and comprising at least 3% of the total mass of the block copolymer, and the block copolymer having a molecular weight of at least 2000, wherein the process step comprises at least one aromatic diol or aromatic diene. An alkoxide compound, optionally in the presence of at least one aromatic dihalo compound, one of which contains at least one sulfone group, and at least one alkali in at least one aprotic solvent; Preparing each of the above homoblocks by reacting in the presence of Both reacted to the homoblock at least aprotic solvent, comprising the step of end-capping said block copolymer optionally followed. The present invention also relates to the block copolymer itself, which is useful for molding, extrusion, and can also be used as a compatibilizer for their high molecular weight homologues. |
