Abstract:

Hydrophobically modified water-soluble ion-containing cellulosic polymer possessing intra-or intermolecular modes of hydrophobic associations has been recently the object of our research[1-4]. Based on the preparation of the surface-active monomer, dimethyloctyl (2-methacryloxyethyl)ammonium bromide (DMOA), new cellulosic graft terpolymers (NCGT) have been synthesized by grafting acrylamide (AM) and DMOA onto carboxymethyl cellulose (CMC) using potassium persulfate and dimethylaminoethyl methacrylate as the initiating system, and characterized by FTIR, elementary analysis, titration and GPC. To obtain the optimum reaction conditions, the influence of the feed ratio and addition order of raw materials, the concentration of initiators, temperature and pH on the grafting have been investigated.
