In this research, a novel MgCl2-supported TiCl4 catalyst in conjunction with bifunctional internal donor was synthesized. The effects of internal donor on propylene polymerization behaviors and polymer properties (morphology, Mw and MWD) were investigated. It was found that the activity of novel catalyst was higher than that of the traditional DIBP-based Ziegler–Natta catalyst, while the catalyst...
The rice starch viscosity characteristics, which can be indicated by Rapid Visco Analyzer profile (RVA profile), have been proved useful for the evaluation of cooking and eating quality in rice breeding program. To study the inheritance of the RVA profile, an F 2 population of Wuyujing 3/Aichi 106 was used. The results indicated that the peak viscosity (PKV) was a typical quantitative character,...
