ʷ The crystal structures of Nylon 6 films with the changes of pressure, temperature, and the processing time were examined. The accompanying physical property changes such as the weight fraction, the crystallinity, the crystal size, the initial modulus, and the thermal properties, gives the following results. When the sample is processed at 16, the weight fraction is not changed significantly with varying pressure. However, at 18 a significant change of the weight fraction was found with increasing pressure above 5 ton/in so as to increase the crysallinity. As long as the ct transition is concerned we found that it begins from 14 and is completed at 18 and 9 ton/ of pressure with the processing time of 120 min. The increase of the initial modulus is believed to be due to the increase of the number of the tie chains and the tension resulting from the change of the crystal size in the direction perpendicular to the direction of the applied pressure. The meltiong point change is due to the pressurized crystallization was not observed.
