Abstract:
A process which comprises free radically copolymerizing a monomer mixture comprising:a) a mono-ethylenic monomer, b) a multi-ethylenic monomer, and c) a mono-allylic monomer selected from the group consisting of allyl and methallyl alcohols, ethoxylated allyl and methallyl alcohols of 1 to 5 oxyethylene units, and propoxylated allyl and methallyl alcohols of 1 to 5 oxypropylene units; wherein the mono-allylic monomer is used in an amount within the range of about 5% to about 40% by weight of the total monomers to produce a copolymer having a weight average molecular weight (Mw) greater than about 10,000, a molecular weight distribution (Mw/Mn) greater than about 5, and a gel content less than about 10% by weight.
