Crystallinity of polymers

摘要

This poster illustrates a new simple procedure to determine temperature dependent percent crystallinity of a polymer. The procedure utilizes Differential Scanning Calorimetry to determine the heat capacity of a polymer and combines that information with information from the Advanced Thermal Analysis Laboratory (ATHAS) (1) data bank. This procedure assumes (consistent with ATHAS data) that the heat capacity contribution of the amorphous content can be extrapolated from the melting region to substantially lower temperatures. This poster explains and illustrates examples of this important new technique.
