Orientation-induced Nucleation in Polymer Crystallization

Abstract

IT is a well-known fact that the crystallization kinetics of polymers crystallizing from the melt are influenced by the mechanical history of the sample1,2. Strain-free samples show a larger crystallization half-time than samples in which the strain has not been completely removed by relaxation at a suitable temperature3,4. A larger number of nuclei has been assumed to be present in strained samples than in strain-free ones. This has been called “orientation-induced” or “stress-induced” nucleation.
