Abstract
In order to minimize the occurrence of heterogeneities, or segregation, of polyethylene and poly(ethylene-d4) in mixed-crystal systems during melt crystallization, it has been found that conditions of high molar ratio of PEH/PED and a small difference in melting points between the two species are necessary. Under these optimum conditions the infrared spectral results observed in melt-crystallized polyethylene have to be attributed predominantly to chains which fold essentially with adjacent reentry along (200) planes.This publication has 9 references indexed in Scilit:
