用红外光谱和X-射线衍射研究了室温拉伸的聚乙烯,结果显示单斜晶存在于室温拉伸的聚乙烯中。对Hendra等关于拉伸过程机理的“微熔融”理论及其所根据实验结果提出异议,而本文的,实验结果支持了Peterlin模型。
The monoclinic form of crystal in the room temperature-drawn high density polyethylene has been examined by Infra-red spectroserny and X-ray diffraction. The results show that the monoclinic form of crystal still exists in the specimens drawn at ligh fate even up 8.5 mm/s. It gives direct support to the peterlin's model for the mechanism of plastic elongation of semicry-stalline polymers.
