WebIn polymer science, degradation generally refers to a complex process by which a polymeric material exposed to the environment and workload loses its original properties ( Horie et al., 2004 ). Degradation is usually an unwanted process. In certain cases, however, controlled polymer degradation is useful. Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation. Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by differe…
