Abstract
A novel gasoline-soluble reaction product, a concentrate comprising the reaction product dissolved in a hydrocarbon solvent, and a haze-free, deposit-resistant and ORI-inhibited motor fuel composition comprising the reaction product is described. The reaction product is obtained by reacting a dibasic acid anhydride, a novel diamine containing block copolymers with polyoxyalkylene backbones, and a hydrocarbyl polyamine. Motor fuel compositions containing the reaction product additive of the instant invention are haze-free and show improved deposit-resistance and ORI control in comparison with motor fuels without the reaction product. Motor fuel compositions of the instant invention may optionally comprise a polyolefin polymer/copolymer component having a molecular weight range of about 500-3500.
