Polypropylene (PP) random copolymers are an important class of commercial materials that can be tuned for a wide range different applications. The structure–property relations mainly discussed in this article focusing on two major influencing factors, the catalyst system and type amount comonomer. Ziegler–Natta (ZN) systems still dominate production polypropylene todays sixth-generation ZN cata...

The present research focuses on investigation of the catalytic behaviors of MgCl₂-SiO₂/TiCl₄/THF Ziegler-Natta (ZN) catalysts with fumed SiO₂ variously treated with silane compounds. The non-treated silica (NTS) and other silicas treated with dimethylsilicone fluid (TSDMSF), dimethyldichlorosilane (TSDMDCS), and hexamethyl-disilazane (TSHMDS) were employed. It was found that the Cat-TSDMDCS and...

The deconvolution of the molecular weight distribution (MWD) polyolefins into Schultz–Flory most probable distributions has become standard method to identify number site types on multiple-site-type olefin polymerization catalysts such as Ziegler–Natta, Phillips, and some supported metallocenes. This been used quantify effect conditions catalyst formulations polyolefin MWD kinetics. Related met...
