ISOTHERMAL CRYSTALLIZATION STUDIES ON NEODYMIUM OXIDE FILLED NYLON-6

Melt mixing of nylon 8 with neodymium oxide particles was carried out with a single-screw extruder. The crystal behaviors of plain nylon 6 a nd the neodymium oxide filled nylon 6 mixture were studied by means of isothermal crystallization kinetic analysis. Isothermal crystallizati on thermograms obtained by differential scanning calorimetry (DSC) wer e analyzed based on the Avrami equation. The neodymium oxide particles acted as a nucleating agent in the mixture. The overall rate of di-is othermal crystallization of the neodymium oxide filled nylon 6 mixture is higher than that of plain nylon 6. The mechanism and modes of plai n nylon 6 were the same as those of neodymium oxide filled PA6 mixture .
