CURABLE POLYMER COMPOSITIONS AND THEIR PREPARATION

摘要

A curable acrylic polymer composition useful in coating, sealant or adhesive compositions comprises an acrylic polymer containing pendant functional groups selected from epoxide groups, isocyanate groups, alkoxysilane groups and activated -CH- groups bonded to at least two electron-withdrawing groups and a curing agent which is reactive with the functional groups of the acrylic polymer and is characterized in that the polymer is dissolved in an organic compound of viscosity less than 2 Pas (20 poise) at 25° C. containing at least one functional group of the same functionality as that present in the acrylic polymer. The composition can be prepared by the free radical polymerization of a functional olefinically unsaturated monomer, and optionally one or more ethylenically unsaturated comonomers, in the presence of the said functional organic compound as diluent.
