Abstract
Very high molecular weight poly(vinylamine) was prepared by a modified Hofmann rearrangement of poly(acrylamide). The reaction was carried o ut in ethylene glycol using the monosodium salt of this solvent and br omine instead of sodium hypohalogenides in the original Hofmann rearra ngement. Poly(vinyl 2-hydroxyethylurethane) was formed as an intermedi ate product. Hydrolysis of the latter gave poly(vinylamine) with quant itative conversions.
