Polyamide blends by reactive processing |
摘要 |
Disclosed is a process for the preparation of a thermoplastic polymer blend comprising a first preformed thermoplastic polymer such as a polyester, polycarbonate, ABS graft polymer and the like and a second thermoplastic polyamide or polyamideimide. The second polymer is prepared from a diisocyanate and polycarboxylic compund selected from a dicarboxylic acid, tricarboxylic acid or anhydride thereof, or mixtures of these components by reactively processing the monomer components in the presence of the first polymer.
