Abstract

The orientation crystallization behavior of linear polymers is significant not only from basic view point of crystallization kinetics but also from engineering view point, such as fiber spinning and its resulted properties. Since early works by Singer et al. (1, 2) and Thiessen (3), the investigation of the rate of orientation crystallization of natural rubber vulcanizates has been performed by several authors using different techniques over considerably wide ranges of crystallization temperature and degree of stretching of bulk specimens (4–8).
