Abstract

1336061 Copolymers containing sulphonate groups ILFORD Ltd 12 Jan 1972 [3 Feb 1971] 3827/71 Heading C3P [Also in Division G2] A copolymer latex is prepared by polymerizing methyl acrylate and sodium γ-allyloxy-#- hydroxy propyl sulphonate in an aqueous medium comprising alkyl aryl polyglycol sulphate as a surfactant, potassium persulphate as a catalyst with sodium bisulphite. In alternative examples the monomers are (1) ethyl acrylate, acrylonitrile and sodium methallyl sulphonate and (2) ethyl acrylate, methyl methacrylate and sodium γ-allyloxy-#-hydroxypropyl sulphonate. Further examples of the sulphonate monomer given are sodium allyl sulphonate, sodium #-allyloxy ethyl sulphonate, and sodium γ-allylthio-#-hydroxy propyl sulphonate.
