A copolymer composition comprising water insoluble graft copolymer particles, wherein the graft copolymer particles comprise: (a) from 2% by weight to 90% by weight of the macromonomer based on the total weight of the copolymer in which the macromonomer is insoluble in water and comprises 10 to 100 polymerized units of at least one monomer with ethylenic installation, less than 1 mol% of the polymerized mercapto-iolefin compounds and less than 5% by weight of the polymerized acid-containing monomer; and (b) from 10% by weight to 98% by weight and the polymerized units of at least one second monomer with ethylenic installation based on the total weight of the copolymer. |
