Study on the Non-isothermal Crystallization Kinetics of Branched Polypropylene [PDF]

open access: yesPolymer Korea, 2012
Branched polypropylenes (PP) with long chain branch were prepared by solid state reaction with three different branching agent of 0.3 wt% content. The chemical structures, non-isothermal crystallization behavior and complex viscosity of the branched PP were investigated by FTIR, DSC, optical microscope, and dynamic rheological measurement. The chemical
