THE CRYSTALLINITY OF POLYOLEFINS
Abstract
Recently a new and simple method for determination of crystallinity of polyethylene and polypropylene was presented by P. H. Hermans and his co-worker. In this laboratory, his method was applied to some samples of polyethylene and polypropylene, and the results compared with other data obtained by means of x-ray and infrared absorption methods. The method consists of an adoption of quantities proportional to the crystalline and amorphous contents, and obtaining a linear relationship between them APPLICABLE TO OTHER SAMPLES. In the case of polyethylene the integrated intensity of the (110) and (200) peaks was selected as a quantity proportional o the crystalline region and the integrated area or height of amporphous peak at theta = 19.60 degrees for hat of the amorphous region.
