摘要
在不同的实验安排中，通过5至360K的绝热量热法测定了两个聚乙烯样品的热容，一个是密度为0.973 g cm-3的线性样品，另一个是0.91 g cm-3密度的支链样品，然后用于研究该系列中的其他聚乙烯样品。这两个样品的热容行为证实了对具有相应密度的样品的期望。
Heat Capacities of Polyethylene III. One Linear and One Branched Sample from 5 to 350 K.
Heat capacities of two polyethylene samples, one linear with a density of 0.973 g cm-3 and one branched with a density of 0.91 g cm-3, have been determined by adiabatic calorimetry from 5 to 360 K in a different experimental arrangement then employed for studies of other polyethylene samples in this series. The heat capacity behavior of these two samples confirms expectations for samples with corresponding densities.
