【Abstract】 he influence of heat treatment on polyamide 1010 structure of aggregatied state was studied by means of WAXD and SAXS techniques.The results showed thatcrystallinity is better at annealing temperature nearby T=175℃ for polyamide 1010 samples,Tg was approximately 58℃ through extrapolating the Wcnx VS.T curve to Wc,x.=0,which is in agreement with the literature.Based on one dimensional electron density correlation function of partially crystalline polymers,the long period L,thickness of the crystalline lamella d,thickness of the transition zone and density difference between crystalline and amorphous regions as well as density Pc of crystalline phase can be directly derived by SAXS data for polyamide 1010 under various annealing temperatures.更多还原
