Thermal characterization of modified linear and long-chain branched polypropylene blends
Original language description
Crystalline structure of linear isotactic polypropylene (L-PP) has been a subject of research for many years and is quite well described at this point. Introduction of long-chain branches (LCB) into polypropylene has proven to influence the final structure in very significant way. The high selfnucleating capabilities of branches in LCB-PP introduce enormous number of nuclei during growth and due to this effect, blends of LCB-PP and linear iPP were produced to study nucleating capabilities of LCB-PP. This study extends the scope of work done by Tian et al. (Tian et al., 2007) and Zhao et al. (Zhao et al., 2012, 2013) with analysis of the nucleation effect of LCB-PP in polypropylene blends and LCB-PP’s interaction with commercially used nucleating agents for iPP in non-isothermal conditions and creates basis for evolution of crystalline structure modeling during conventional processing methods, such as injection molding and extrusion. Taking in account different crystallization kinetics for α and β phase as well as the presence of LCB, a modified Nakamura equation was implemented to describe the crystallization and obtain the modelling parameters for further industrial use.
