Abstract

Branched polymers are prepared by mixing together monofunctional vinylic monomer with from 0.3 to 100% w/w of polyfunctional vinylic monomer and from 0.0001 to 50% w/w of chain transfer agent and thereafter reacting the mixture to form a polymer. The resulting branched polymers are soluble and may be used as component of surface coatings and inks as well as molding resins.
