采用吸光度减法技术从半结晶聚合物的光谱中分离出了等规聚丙烯在优选的31螺旋构象和无定形相的不规则构象中的红色特征带。有序分量的频谱提供了关于频带分配的新信息。非晶相的光谱已被比较的熔体的光谱。前者的某些特征可以归因于熔融淬火样品的无定形相中的有序构象的程度。
Infra-red bands characteristic of isotactic polypropylene in the preferred 31helical conformation and in the irregular conformations of the amorphous phase have been isolated from the spectrum of the semicrystalline polymer using the absorbance subtraction technique. The spectrum of the ordered component makes available new information concerning band assignments. The spectrum of the amorphous phase has been compared to the spectrum of the melt. Certain features of the former can be attributed to a degree of ordered conformation in the amorphous phase of a melt-quenched sample.
