REACTION PRODUCT ADDITIVE AND ORI-INHIBITED MOTOR FUEL COMPOSITION (D#78,679-C1 -F) ABSTRACT A novel gasoline-soluble reaction product, a concen- trate comprising the reaction product dissolved in a hydrocar- bon 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.
