Abstract
Novel N-(vinylphenyl)sulfonamides and polymers thereof including copolymers of N-(vinylphenyl)sulfonamides and styrene are prepared by reacting 4-vinylaniline with an amine and a sulfonyl chloride in the presence of an acid acceptor to produce the monomer to be polymerized. The homo- and copolymers of these N-(vinylphenyl)sulfonamides are useful as vesiculating matrices in vesicular elements.
Claims4
A N-(vinylphenyl)sulfonamide having the formula:
- ##STR4## wherein R is selected from the group consisting of alkyl or substituted alkyl containing from 1 l to 10 carbon atoms and aryl or substituted aryl containing from 6 to 10 carbons atoms, said substituents being selected from those which do not adversely affect the vesicular properties of any polymer or copolymer formed from said N-(vinylphenyl) sulfonamide.
