Polyalkylene glycol block copolymers containing phosphorous groups and their use as emulsifiers in emulsion polymerization

摘要

Aqueous polymer dispersion comprises (A) 1-70 wt.% a polymer made of at least one olefinically unsaturated monomer and prepared by emulsion polymerization, (B) 0.01-7 wt.% at least one polyalkylene glycol block copolymer (I), and (E) water. Aqueous polymer dispersion comprises (A) 1-70 wt.% a polymer made of at least one olefinically unsaturated monomer and prepared by emulsion polymerization, (B) 0.01-7 wt.% at least one polyalkylene glycol block copolymer of formula (I), and (E) water. A : H or -PO 3M 2; M : H or sodium-, potassium- or ammonium ion; m : 1-100; and n : 3-100. [Image].
