METHODS OF POST-POLYMERISATION EXTRUDER INJECTION IN CONDENSATION POLYMER PRODUCTION
摘要
The invention is a novel method for the late introduction of additives into condensation polymers. The method employs a reactive carrier that functions as a delivery vehicle for one or more additives. The reactive carrier reacts with the condensation polymers, thereby binding the reactive carrier in the polymer resin and preventing the emergence of the reactive carrier from the polymer resin during subsequent thermal processing.
