Uses
Sodium methallyl sulfonate was used as anionic monomer to investigate the effect of different cationic or anionic moieties in acrylonitrile-based copolymers on the interaction with fibroblasts.
Sodium methallyl sulfonate was used to reduce the homopolymerization during graft copolymerization of methyl methacrylate with water-emulsified solution onto preirradiated jute fiber.

Synthesis
The synthesis of Sodium methallyl sulfonate is as follows:The neutralization was carried out with sodium carbonate to pH 7.
The neutralized filtrate was evaporated under reduced pressure (20 mmHg) to remove water and to obtain 46.5 g of white crystalline sodium methallyl sulfonate.
The product was identified with a standard sample by IR spectrum.
The purity of the product was 95.5% and the yield 95%.
