Abstract:
A water-soluble or water-dispersible polymer which is obtained by subjecting(a) ethylenically unsaturated monomers to free-radical polymerization in the presence of (b) polyalkylene oxide-containing silicone derivatives of the formula I where: R6 is an organic radical of 1 to 40 carbons which may contain amino, carboxyl or sulfonate groups, or, if c=0, is the anion of an inorganic acid, and where the radicals R1 can be identical or different and alternatively derive from the group of aliphatic hydrocarbons of 1 to 20 carbons, are cyclic aliphatic hydrocarbons of 3 to 20 carbons, are aromatic in nature or are R5, where: â€ƒwith the proviso that at least one of the radicals R1, R2 or R3 is a polyalkylene â€ƒoxide-containing radical as defined above, â€ƒand n is an integer from 1 to 6, â€ƒx and y are integers such that the molecular weight of the polysiloxane block is from 300 to 30,000, â€ƒa, b can be integers from 0 to 50 with the proviso that the sum of a and b is greater than 0, and c is 0 or 1.
