Abstract
  MgCl2 supported Ti catalyst is used in commercial propylene polymerization process. Morphology is a key performance determination parameter for polymer resins produced by commercial olefin polymerization process. Higher resin flowability and bulk density (greater than 0.38g/cc) are demonstrated by ‘good’ ...  Read More

Parthiv M. Trivedi; Sandip Patil; Virendra K. Gupta

Volume 11, Issue 1 , February 2024, , Pages 21-28

https://doi.org/10.22063/poj.2023.3455.1274

Abstract
  Ultra-high molecular weight polyolefin (UHMWPO) has enormous potential applications due to their excellent mechanical properties such as tensile strength, flexural modulus, toughness and outstanding chemical resistance. But the processing of polyolefin, in particular, UHMWPO fibers cannot be processed ...  Read More

Olefin polymerization and copolymerization

Hiren Bhajiwala; Virendrakumar Gupta

Volume 11, Issue 1 , February 2024, , Pages 61-70

https://doi.org/10.22063/poj.2023.3483.1279

Abstract
  Ultra-high molecular weight polyethylene (UHMWPE) was synthesized using Bi-supported SiO2/MgCl2/TiCl4 (Si-Mg-Ti) Ziegler-Natta catalyst in conjugation with triethyl aluminum (TEA). The impact of temperature and the presence of a chain-terminating agent were examined in the context of ethylene polymerization. ...  Read More

Volume 10, Issue 4 , November 2023, , Pages 235-242

https://doi.org/10.22063/poj.2023.3449.1272

Abstract
  The copolymerization of methyl acrylate (MA) and glycidyl methacrylate (GMA) with 1-hexene was carried out using activator regenerator by electron transfer atom transfer radical polymerization (ARGET ATRP) employing Cu(0)/CuBr2 as a catalyst, pentamethyl diethylenetriamine (PMDETA) as a ligand, and ethyl ...  Read More
