  • Patent number: 7498395
    Abstract: A method of preparing a (meth)acrylate functionalized polymer comprising the steps of mixing together a monofunctional vinylic monomer with from 0.3-100% w/w (based on monofunctional monomer) of a polyfunctional vinylic monomer and from 0.0001-50% w/w of a chain transfer agent, reacting said mixture to form a polymer and terminating the polymerization reaction before 99% conversion. The resulting polymers are useful as components of surface coatings and inks, as moulding resins or in curable compounds, e.g. curable moulding resins or photoresists.
    Type: Grant

  • Patent number: 7244796
    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.
