SUBSTITUTED ALKOXYLATED PHENOLS AND BRANCHED SULPHATES FOR USE IN EMULSION POLYMERIC LATEX Russian patent published in 2010 - IPC C08K5/02 C09D133/06 C08F20/10 C09J133/06 

FIELD: chemistry.

SUBSTANCE: invention relates to emulsion polymeric latex, particularly latex used in pressure-sensitive adhesives, paints and coatings. The paint composition contains at least one emulsion polymeric latex obtained from a surfactant composition containing at least one polystyryl phenol-based surfactant and synthetic monomers selected from a group consisting of at least one vinyl aromatic component, at least one acrylic acid component, at least one methacrylic acid component, at least one acrylic or methacrylic ester component, derivatives and combinations thereof. Surfactant compositions for use during synthesis of at least one emulsion polymeric latex contain at least one branched surfactant, at least one surfactant with a three-dimensional structure or a mixture of branched surfactant and a surfactant with a three-dimensional structure. One preferred surfactant composition contains at least one alkoxylated polyaryl-substituted aromatic compound. Another preferred surfactant composition contains at least one branched alkyl sulphate and at least one ethoxylated polystyryl phenol. Another preferred surfactant composition contains at least one sulphonated polystyryl phenol. Paint films made from latex have high resistance to wet cleaning with a brush, high adhesion and resistance to bubble formation.

EFFECT: adhesives are permanent at room temperature in dry form.
