PROCESS FOR THE PREPARATION OF HYDROXY FUNCTIONAL POLYMER AND ITS USE IN COATING COMPOSITIONS

摘要

The present invention relates to a process for the preparation of hydroxy functional polymer and its use in coating compositions. More in particular the invention relates to a process comprising the radical polymerisation of ethylenically unsaturated monomers in presence of hydrogen peroxide. The said resin composition has to contain from 5 to 45 weight % of an unsaturated radical-polymerisable carboxylic acid. The acid functional made resin is subsequently reacted with a mono-epoxy functional derivative.
