Abstract
The present invention relates to a branched vinyl polymer carrying dendrons made from monofunctional vinyl monomers and branched by virtue of difunctional vinyl monomers so that there is on average one branch or fewer per polymer chain to avoid gelation. The polymer may be made by chain-growth polymerization of predominantly monofunctional vinyl monomers in the presence of difunctional vinyl monomers and dendron units.
