Abstract
The invention relates to a polymer dispersion, by means of which the rheological properties and structure of various liquid and flowing mixtures may be adjusted. The dispersion is prepared by radical polymerizing, into a water soluble chain backbone polymer or into such a polymer brought water soluble, in a water solution at least one .alpha.-, .beta.-unsaturated carboxyl acid containing 3-8 carbons as well as at least one to a limited amount unsaturated monomer. The chain backbone polymer is preferably a starch derivative.
