Crystallization of Polymers SpringerLink

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 19, 2012 · In Crystallization of Polymers, 2nd Edition, Leo Mandelkern provides a self-contained, comprehensive, and up-to-date treatment of polymer crystallization.

WebAbout this book. Since the discovery that polymer single crystals are composed of chain folded macromolecules in 1957, the crystallization of polymers has attracted considerable interest and still provides fascinating and fruitful areas of research. Only a few books have been fully devoted to the crystallization of polymers in the past. Web21 hours ago · Water induces the crystallization of ZnPBIm-g to an unknown crystalline phase [Fig. 3(c-vii)]. By using a mixture of water–toluene or water–ethanol with a water content of 2% by volume, we observed the crystallization of ZnPBIm-g to crystalline ZnPBIm [Figs. 3(c-v) and 3(c-vi)]. The above-mentioned results suggest that a suitable … canaan vt post officeWebIn 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. fish bidding
