Crystallization of polymers 2nd
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 different analy… WebJul 1, 2013 · Polymeric crystals are more complex in nature than other materials' crystal structures due to significant structural disorder present.

WebIn addition, the PLA-SA-PBS molecules preferentially support crystallization of PBS phase with increased degree of crystallinity (X c,PBS) by ~15%. These enhanced homogeneity of PLA/PBS/SA blend and high X c,PBS trigger the increased tensile strength to 50 MPa, and substantially reduced oxygen permeation coefficient approximately 10 times.
