## Abstract Application of shear is found to increase the rate of solution polymerization of acrylonitrile in N,Nβdimethyl formamide (DMF) initiated by benzoyl peroxide by as much as 400 percent of the value in absence of shear. The solvent DMF acts as an inert and maintains a homogeneous reaction
## Abstract The apparent viscosities of aqueous solutions of sodium carboxymethylcellulose (NaCMC) and __k__βcarrageenan have been measured over a range of shear rates from 14 to 1142 s^β1^. Comparable measurements were also made on gum solutions to which glucose, sucrose, or glucose syrup had been
