A new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. In this study potassium persulfate system was used for initiation the polymerization. Graft polymerization of acrylonitrile (AN) onto starch (Sta) was carried out in aqueous solution using potassium persulfate (I) redox system. It was found that the percentage of grafting and rate of gr...

Cellulose was modified by polystyrene (PS) and polyacrylonitrile (PAN) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. For this purpose, first, the graft polymerization of styrene (St) onto cellulose fibers was performed by using suspension polymerization and ...

The kinetics of acrylic acid (AA) solution polymerization was investigated by polymerizing 30 wt % aqueous AA solutions at pH values ranging from 2.2 to 9.9. The polymerization rate was determined with differential photocalorimetry and was found to be a strong function of the solution pH and the ionic strength. Although the polymerization rate decreased with increasing pH below pH 6.5, an incre...
