Abstract
Abstract A new class of highly reactive vinyl-polymerizable monomers having surfactant properties is provided by the esters of acrylic, methacrylic and crotonic acids and the mono- and di-esters of maleic, fumaric, itaconic and aconitic acids with (a) C 8 - C 20 alkylphenoxy (ethyleneoxy) 10-60 ethyl alcohol, (b) (ethyleneoxy) 15-25 sorbitan esters of C 12 - C 20 fatty acids and (c) methyl cellulose, hydroxymethyl cellulose hydroxyethyl cellulose and polyvinyl alcohol. The new surfactive monomers are used in emulsion polymerization to provide latexes and copolymers with superior properties.
