本文采用差热分析(DTA)、差示扫描量热法(DSC)研究了一系列以高效催化聚合而得的初生态超高分子量(_w=70—315×10~4)聚乙烯粉的热熔行为,还研究了在接近熔化或部分熔化的温度下恒温热处理对晶体性质的影响.
In this paper, differential thermal analysis (DTA) and differential scanning calorimetry (DSC) were used to study the thermal behaviors of a series of ultra-high molecular weight polyethylene powders (_w = 70-315 × 10 ~ 4) Melting behavior was also studied and the effect of constant temperature heat treatment on the properties of the crystals at or near the melting temperature was also investigated.
