ORIENTATION STUDIES ON DRAWN POLYOLEFINS II

Abstract

The x-ray diffraction, birefringence and stressstrain curves for polybutene-1 and polypentene-1 have been studied for q) (Contract Nonr-335700, Proj. NR 356-37 ) Unclassified report DESCRIPTORS: (Polymers, Films, *Butenes, *Pentenes, X-ray diffraction analysis, Mechani cal properties, Crystal structure, Stresses, Molecular structure, Density, Tensile proper ties, Theory.) (Polymers, *Ethylenes.) The x-ray diffraction, birefringence and stressstrain curves for polybutene-1 and polypentene-1 have been studied for quenched and annealed samples. The variation of crystalline orientation functions with elongation is calculated for polybutene-1. Differences among the variations of birefringence with degree of elongations of these polymers are compared with those for polyethylene and polypropylene and are discussed in terms of differences in molecular structure. Mechanical property variations are discussed in terms of differences in orientation properties. (Author)
