【発明の名称】水性コポリマー分散液
Document Type and Number:
Japanese Patent JP3352692
Kind Code:
B2
Abstract:
Aqueous copolymer dispersions are obtained by radical initiated copolymerisation or by copolymerisation initiated by the use of ionising radiation of: (A) 40 to 99 % by weight of one or several water-insoluble, monoethylenically unsaturated monomers; (B) 1 to 60 % by weight of one or several water-soluble, monoethylenically unsaturated monomers; and (C) 0 to 30 % by weight of one or several ethylenically polyunsaturated monomers, in an aqueous medium in the presence of 2 to 20 % by weight, in relation to the total monomer amount, of surface active compounds as emulsifiers. These dispersions have a mean particle size from 5 to 37 nm as determined by light scattering in the aqueous medium. Such dispersions are suitable for preparing varnishes, paints and adhesives, as film-builders in hair-care cosmetic compositions, as protective media against ultraviolet light and as carriers for substances contained in pharmaceuticals, cosmetics or agrochemicals.
