<p>A copolymer comprising (a) from 40 to 95 mole percent maleic anhydride, a portion of which has been modified to the structure (I) or (II), wherein R is R1 or R2, wherein R1 is H or C1 to C18 linear, branched, or cyclic alkyl, or C1 to C18 alkyl substituted with C1 to C4 alkoxy, and R2 is R3-(SO3M)n, wherein R3 is C1 to C10 straight or branched alkyl, M is Na, K, Li, NH3, H and n is 1, 2 or 3; such that between 5 to 100 % of the maleic anhydride of the copolymer comprises said modified maleic anhydride, and the ratio of R1 to R2 in the modified maleic anhydride portion is between 10:1 and 1:10; and (b) from 5 to 60 mole percent alpha olefin having the structure (1), wherein R4 is a C5 to C30 straight or branched alkyl. The invention also provides an emulsion polymerization system comprising a polymeric stabilizer, wherein the polymeric stabilizer comprises on or more of the copolymers of the invention, and provides a polymer produced by the emulsion polymerization system of the invention.</p> |
