摘要：

A study was made of the ceric-ammonium-nitrate-initiated graft copolymerization of polyacrylamide onto hydroxypropyl guar gum by solution polymerization technique. Six grades of graft copolymers have been synthesized by varying catalyst and monomer concentrations. The synthesized products were then characterized by various instrumental techniques Like viscometry, elemental analysis, IR, thermal, XRD and SEM studies. The percentage of grafting increases with increasing catalyst concentration and decreases with monomer concentration taking other parameters constant. (C) 2001 Elsevier Science Ltd.
