The weight conversion at the gel point (~) was determined by the gas bubble method in two sets of polyacrylamide (PAA) gels crosslinked with N,N'-methylene-bisacrylamide (BA). ~t~ remained practically constant when the crosslinker ratio was C = 10% (w/w) and the total concentration of comonomers in
Acrylamide and N,N-methylenebis(acry1amide) (AAm-Bis) copolymerization has been investigated in water at a monomer concentration of 1.8 w/v %. Conversion of monomer and pendant vinyl groups was measured as a function of the reaction time up to the onset of macrogelation. Experimental results indicat
