Effects of monomer length on α‐olefins polymerization using a conventional Ziegler–Natta catalyst

Abstract: α-Olefin monomers with different lengths from C 4 to C 10 were polymerized via a conventional Ziegler-Natta catalyst. It was found that activity of the catalyst decreases with increase in the monomer length as well as introduction of external donor. GPC results exhibited a steady decrease in molecular weight from poly1butene to poly1-decene; however, PDI did not show a clear trend. Based on differential scanning calorimetry and X-ray diffraction analyses, poly1-butene and poly1-decene represented crystalline s… Show more

“…The decrease in oligomerization energy is due to the sterically hindered side chain, which affects oligomers formation. The exceptional behavior of octene has also been observed by Shirbakht and coworkers 56 . They have reported the effect of monomer length on polymerization of polyolefins using the Ziegler‐Natta catalyst 56 .…”

“…In this study we focus on the backbone, in particular on the study of how the absence of ether bonds in the polymer matrix improves the chemical stability of anion exchange ionomers, synthesizing the copolymer poly(VBCl-co-hexene). We chose the Ziegler-Natta polymerization (ZNp) because this technique of polymerization is the most suitable for the synthesis of poly alpha-olefins [35] and co-polymerization of alpha-olefins with styrenic monomers [36]. It has also been employed for the homopolymerization of styrenic monomers [37].…”

“…Polymer blending is usually known as physical mixing of two or more homopolymers or copolymers to improve physical, mechanical (especially toughness), thermal and other important properties for particular applications [7][8][9][10][11][12]. Lots of polymers are available to enhance PLA properties like polyethylene glycol, polycarbonates (PCs), polystyrene, poly(ethylene-co-glycidylmethacrylate), polyethylene, polypropylene, polymethyl methacrylate, poly(acrylonitrile-butadiene-styrene), polyvinyl acetate, starch and so on [12,13].…”
