Abstract
A polymeric surfactant formed by the reaction of an oligomeric or polymeric substrate with at least one ethylenically unsaturated monomer, wherein the reaction is conducted in the presence of a type II photo initiator and by the action of actinic radiation. The polymeric surfactant is useful for stabilising the interface in emulsions or dispersions.
