中文摘要	the melting behavior of drawn, compression-molded isotactic polypropylene has been examined in terms of the influence of drawing conditions on the observed properties. two endothermic peaks were observed on differential scanning calorimetry (dsc) for samples when high draw ratios and high heating rates were used during dsc tests. the peak at lower temperature is influenced by draw ratio, temperature, and rate, and exhibits a strong superheating effect. the species associated with this peak can partially recrystallize into another species associated with the peak at higher temperature during dsc measurements. the position of the peak at higher temperature depends only on draw ratio. it is proposed that the double-melting peaks at lower and higher temperature result from extremely thin quasi-amorphous or crystalline layers between microfibrils and the lamellar crystals within microfibrils, respectively.
