Abstract
Styrene-maleic acid and styrene-itaconic acid copolymers were chlorosulfonated and subsequently reacted with 2-chloroethylamine to give N-(2-chloroethyl) sulfonamides of these copolymers.
Products containing about 0.5 of N-(2-chloroethyl) sulfonamide group per phenyl group were obtained. The derivatives are soluble in alkali to give viscous solutions.
Cotton fabrics treated with the alkaline solution of the derivative were found to increase in weight by 6_??_10 percent, and the polymer attached to the fibers was not shed by the ordinary soaping. It is considered that the polymer combines chemically with the fibers.
The N-(2-chloroethyl) sulfonamides of the polymers may be utilized as reactive paste and adhesive.
