“…By comparing the signals of methyl protons from cis ‐1,4‐units at 1.51 ppm and those from trans ‐1,4‐units at 1.42 ppm, the content of trans ‐1,4‐units in Ip polymer was found to be about 80%. The high trans ‐1,4‐stereospecificity of isoprene polymerization with TiCl 4 /MgCl 2 ‐TIBA catalyst meets well with the literature reports on similar systems …”

“…In this work, we have studied copolymerization of ethylene and isoprene (Ip) with a MgCl 2 ‐supported Ziegler–Natta catalyst designed for industrial production of polyethylene. According to previous works of Huang and He et al, isoprene polymerization catalyzed by Ziegler–Natta catalyst affords nearly 100% trans ‐1,4‐polyisoprene due to excellent stereoselectivity of TiCl 4 /MgCl 2 type catalyst . However, copolymerization of ethylene with isoprene by this type of catalysts has not been reported before.…”

“…The versatile nature of PP in terms of its stiffness, transparency, tensile strength, low production cost and ability to be recycled has made this PP to find numerous applications in a wide variety of fields like packaging industries, electrical, electronic, automobiles etc [2][3][4][5]. Generally, industrial manufacture of PP is derived from Ziegler Natta (ZN) polymerization and ZN catalysts remain the top priority in the olefin polymerization industries [6][7][8][9][10]. For industrial application, mainly three different classes of PP derived from ZN Catalyst are homo, random PP and impact copolymer.…”

“…In this work, a facile method was employed to prepare ethylene–propylene full‐alternating copolymer. Isoprene polymerization catalyzed by Ziegler–Natta catalyst can afford 100% trans ‐1,4‐polyisoprene due to the excellent stereoselectivity for monomer incorporation of TiCl 4 /MgCl 2 ‐supported catalyst, and subsequently, it was hydrogenized by p ‐toluenesulfonohydrazide (TSH) and tripropylamine (TPA), thus ethylene‐ alt ‐propylene copolymer with high molecular weight (MW) was obtained. Compared with other catalysts, Ziegler–Natta catalyst is the most widely used industrial catalyst for polyolefins, therefore, the polymer EP promisingly can be produced on a large scale.…”
