The turbulent drag reduction characteristics of the rod-like polysaccharide xanthan gum dissolved in water was investigated using a rotating disk apparatus. The ultrasonic degra~tion method was adopted to obtain polymer fractions of different molecular weights of xanthan gum for this study. The drag
## Abstract Graft copolymers of acrylamide on cellulose materials (Ξ±βcellulose 55.8%, DP 287.3) obtained from __Terminalia superba__ wood meal and its carboxymethylated derivative (DS 0.438) were prepared using a ceric ion initiator and batch polymerization and modified batch polymerization process
Graft copolymers of carboxymethyl cellulose and starch with polyacrylamide have been synthesized by grafting acrylamide onto carboxymethyl cellulose and starch, respectively, using a ceric-ion-initiated solution polymerization technique. These graft copolymers have been tested for their drag-reducti
