In situ formation and incorporation of additives into polymers during interfacial polycondensation reactions

摘要

AbstractOne of the objectives of the work was to attempt the in situ formation of inorganic fillers during interfacial polycondensation reactions. The complementary components of the filler were added separately to the organic and aqueous phases of the system so that they formed the insoluble filler at the interface simultaneously with the polymer. Since the polyamide plastics have good molding properties, nylon 610 was selected as the principal model, but some work was also carried out with a urethane polymer. Further, coloring of nylon 610 and of a polyurethane resin was investigated by lake formation at the interface with the help of 1,2‐dihydroxyanthraquinone in the organic phase and a metal salt in the aqueous phase. In this way, red‐ and blue‐colored polymers were prepared. Finally, by adding zinc ions to the aqueous and pentachlorophenol to the organic phase, zinc pentachlorophenate was incorporated into nylon 610 during its formation. The ignition point of the resultant product was significantly higher than that of a sample to which zinc pentachlorophenate had been added by mechanical m
