## Abstract Potassium persulfate (K~2~S~2~O~8~) was used to initiate the polymerization of acrylic acid (AA) monomer in a chitosan (CS) solution. Both a poly(acrylic acid) (PAA) homopolymer and a CSβ__co__βPAA copolymer were produced. When the amount of AA was increased from 5 to 40 g with 5 g of C
## Abstract A redox initiator, cerium ammonium nitrate, was used to initiate the graft copolymerization of vinyl acetate (VAc) onto the chitosan chain in a dispersion polymerization at 60Β°C. With an addition of 0.5β7.5 g of chitosan based on 50 g of VAc, the monomer conversion was found to be betwe
