✦ Synopsis

The phase structure and thermal transition of acrylic fibres have been investigated at several temperature increments from 22 to 200°C. Two glass transition temperatures at 82 and 140°C have been identified and corresponded to the structural transitions of the paracrystalline and amorphous regions, respectively. These experimental observations give strong evidence to support the 'limited two-phase' model.
