    摘要: An improved coating composition having one or more polymeric binders dispersed in a liquid medium, wherein the improvement comprises an anti-sag and anti-settling effective amount of a copolymer comprising a polymeric backbone comprising recurring monomeric units derived from monomers selected from the group consisting of one or more .alpha.-olefins and one or more unsaturated carboxylic acids, said backbone having grafted thereto, by a covalent amide linkage, one or more polymeric grafts comprising at least one recurring monomeric unit selected from the group consisting of:--NHC(O)RC(O)NHR.sub.1 and --NH--R--C (O)--or a combination thereof, wherein R is an alkylene group of at least about 2 carbon atom, and R.sub.1 is R or aryl.
