Abstract
Fremgangsmåte for fremstilling av en ikke-vandig dispersjon av addisjonspoly- merer i et alkydmedium, omfattende a) utvelgelse av et alkyd med en mole- kylvekt, Mz, mellom 10 000 og 250 000 og med en polydisper- sitet mellom 2,0 og 20, og b) polymerisasjon av en eller flere monomerer i nærvær av alkydet ved hjelp av friradikal-addisjonsmeka- nismen; idet minst en av monomerene har hydrok- syfunksjonalitet, og hvor polymerisa- sjonen gjennomføres i nærvær av et kje- deoverforingsmiddel.A process for preparing a non-aqueous dispersion of addition polymers in an alkyd medium, comprising a) selecting an alkyd having a molecular weight, Mz, between 10,000 and 250,000 and having a polydispersity between 2.0 and 20 and b) polymerizing one or more monomers in the presence of the alkyd by the free-radical addition mechanism; wherein at least one of the monomers has hydroxy functionality and wherein the polymerization is carried out in the presence of a chain transfer agent.
