【Abstract】 series of 1,4 cyclohexane dimethanol modified poly(ethylene terephthalate) copolymers were synthesized. The isothermal crystallization and crystallinity of these samples were investigated by means of DSC and FT IR. The results show that both the composition and the crystallization temperature tack effect on crystallization behaviors, which might be helpful for controlling and improving the material processing properties.更多还原
