poly(vinyl acetate)-based block copolymer/clay nanocomposites prepared by in situ atom transfer radical polymerization
atom transfer radical polymerization of styrene (st) and methyl methacrylate (mma) was performed at 90oc in the absence and presence of nanoclay (cloisite 30b). trichloromethyl-terminated poly(vinyl acetate) telomerand cucl/ pmdeta were used as a macroinitiator and catalyst system, respectively. the experimental results showed that the atom transfer radical polymerization of st and mma in the a...
متن کاملthe effects of reaction variables on solution polymerization of vinyl acetate and molecular weight of poly(vinyl alcohol) using taguchi experimental design
poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...
متن کاملstudy of ethylene/vinyl acetate transformation to ethylene/vinyl alcohol copolymer by nmr and dsc
hydrolysis of ethylene-vinyl acetate copolymer in alkaline conditions using two systems of naoh/methanol and koh/isopropanol has been studied and the formation of ethylene-vinyl alcohol copolymer was systematically examined using nmr spectroscopy and dsc measurements. vinyl acetate weight percentage and the degree of hydrolysis were calculated from nmr spectroscopy and it is shown that hydrolys...
متن کاملA Kinetic Study of the Emulsion Polymerization of Vinyl Acetate
This report deals with the chemically and the radiation-initiated emulsion polymerization of vinyl acetate. In experiments with potassium persulphate as initiator and sodium lauryl sulphate (SLS) as emulsifier the rate of polymerization is approximately proportional to the square root of initiator concentration and to the 0.25 power of the number of particles. The number of particles is proport...
