Abstract
Data for the specific heat of polyethylene as a function of crystallinity are collected from 1° to 420°K. Specific heats, entropies, and enthalpies of the completely amorphous and crystalline polyethylene are extrapolated. The glass transition is located for the amorphous at 237°K with a ΔCp of 2.1 cal deg—1 (mole CH2)—1. Specific‐heat values at constant volume are calculated for the crystalline polyethylene.Keywords
