Abstract
Nylon 6(N6) and nylon 6(80)-ran-nylon 4(20) (N6-ran-N4) films were prepared using melt pressing methods. The N6-ran-N4 films were drawn uniaxially at various drawing speeds at $125^{\circ}C$, and the film properties were examined by WAXD, DSC, and DMTA. The crystal structure in the N6-ran-N4 films as the drawing speed increased became very similar to the alpha phase of N6. The thermal property of the N6-ran-N4 films prepared with increasing drawing speeds indicated an increasing melting temperature and enthalpy.
