Volume 10, Issue 4 , November 2023, Pages 191-204

https://doi.org/10.22063/poj.2023.3256.1241

Abstract
  The time available for proper casting of the polyurethane (PU) system after isocyanate addition (called pot life) affects the macrodiol microstructure. In this research, the effect of molecular weight ( Mn ) of hydroxyl terminated polybutadiene (HTPB) as an important macrodiol on the pot life of polyurethane ...  Read More

Abstract
  Ethylene-propylene copolymerization reactions were carried out using rac-Et(2-MeInd)2ZrMe2 catalyst and (2,6-tBu2PhO-)AliBu2 as activator under varying reaction conditions. We demonstrate that reaction conditions such as monomer concentration, Al/Zr molar ratio and solvent type (toluene and heptane) ...  Read More
