摘要
通过差示扫描量热测试法和偏光显微镜,研究了相对分子质量和等规度分别对聚丁烯-1(i-PB)结晶度和结晶形态的影响。实验结果表明:在常温结晶时若i-PB的相对分子质量越小则结晶度越高,晶粒完善性越好;同时等规度越高则结晶度越高,晶粒完善性越好。
It is studied that the molecular weight and the isotactieity of the polybutene-1 effected the crystallization morphology and the degree of erystallinity by the differential scanning calorimetry and the polarized right microscope. The results showed： the lower the molecular weight the higher the erystallinity and the better the spherical crystal;the lower the isotaeticity the higher the erystallinity and the better the spherical crystal.
