uspension Polymer Obtained by Polymerization of Vinyl Acetate in Aqueous Solution Using Ammonium Persulfate as Initiator

Synthesis and Evaluation of Chitosan -Polyaniline Copolymer in Presence of Ammonium Persulfate as Initiator

Chemical grafting of Polyaniline (PAni) and chitosan (CS) as has been carried out with formaldehyde as grafting agent and ammonium persulfate as an initiator. For this reason aniline monomers were copolymerized with chitosan and were chemically polymerized. The synthesized copolymer was Characterized using Fourier transform infrared spectroscopy (FTIR), UV-Visible, scanning electron microscopy ...

synthesis and evaluation of chitosan -polyaniline copolymer in presence of ammonium persulfate as initiator

Grafting of Industrial Cellulose Pulp with Vinyl acetate Monomer by Ceric Ion Redox System as Initiator

The Ce/ Ce redox system was studied to initiate the grafting of idustrial cellulose pulp with vinyl acetate monomer. The parameters of the copolymerization reaction (reaction time, temperature, monomer and initiator contentration, freeness, chemical composition of the cellulose) were investigated and their effects are discussed.

prediction of optimum time for oxygen clearance in solution polymerization of vinyl acetate in isopropyl alcohol

as we know oxygen is one of the main inhibitors of polymerization of vinyl acetate. therefore, nitrogen is used in order to make sure of system's high purity. to maintain purity it is necessary to find out the rate of the oxygensolution in polymerization system under different conditions of polymerization. it is concluded that incoming nitrogen to the system would remove the oxygen from th...
