Abstract
In the manufacture of plastics dispersions on the basis of vinyl polymers water-soluble salts of polybasic phosphonic acid derivatives, especially alkane-phosphonic acids and phosphonomethyl amines are used as dispersing auxiliaries. The dispersions obtained are suitable as coating agents and for impregnating, coating or glueing solid materials.
Claims8
An aqueous dispersion of vinyl polymer plastic containing 0.005 to 5% by weight, calculated on the total amount of vinyl monomer(s), of a water-soluble salt of a polybasic phosphonic acid derivative having two to four phosphorus atoms wherein said dispersion contains polymer particles with an average diameter of 0.05 to 5.0 .mu.m.
