[ 1 ] - Separation of Carbon Dioxide from Natural Gas by Matrimid-Based Mixed Matrix Membranes
Spherical MgO nanoparticles and Flake-like clay minerals modified with polyaniline (PAni) are applied in Matrimid in order to fabricate mixed matrix membranes (MMMs) having improved gas separation performance. The CO2 permeability, CO2/CH4 selectivity and CO2-induced plasticization pressure of MMMs are assessed at 4-30 bar feed pressure. The chemical structure, morphology and thermal properties...
[ 2 ] - Response Surface Methodology for Investigating the Effects of Hydrolysis Reaction Parameters on Molecular Structure and Performance of Polyvinyl Alcohol as Primary Suspending Agent
This study presents the synthesis of polyvinyl acetate (PVAc) by solution polymerization and its partial hydrolysis to polyvinyl alcohol (PVA) using alkaline alcoholysis. The influence of the molar ratio of hydrolysis catalyst (NaOH) to PVAc and the time and temperature of the saponification reaction on the degree of hydrolysis and molecular weight of the PVA were investigated using response su...
