Abstract
A curable high solids coating composition containing a reactive acrylic polymer formed from polymerizing an alpha, beta-ethylenically unsaturated monomer containing a functional group such as a hydroxyl group and other non-functional alpha, beta-ethylenically unsaturated monomers is disclosed. The polymer is prepared by organic solution polymerization techniques in an organic solvent and in the presence of t-amylperoxy compound and a 2,4-diaryl-1-alkene. The coating compositions are particularly useful as coatings for automobiles where they can be deposited as non-yellowing clear coats.
