Branched Vinyl Polymers

The copolymerization of hydrophobic vinyl ester of branched neo carboxylic acids significantly improves the performance of vinyl and acrylic binders. Also discovered is a vinyl polymer resin comprised of from 0 1 to 50 weight percent of non linear polymers having at least 0 06 branches 1000 backbone carbons where branching is measured using a heat polymerized polystyrene having from 0 0 to 0 06 branches 1000 backbone carbons as a linear reference. An approach to branched vinyl polymers through radical polymerization in the presence of 3 mercaptohexyl methacrylate mhm as the chain transfer monomer is reported in this paper.
