    摘要： A process for the continuous preparation of lactone-esters which comprises: passing a liquid feed of a branched-chain alkenylsuccinic anhydride containing a chain wherein branching is derived from C.sub.3 to C.sub.10 olefins, and an alcohol in a hydrocarbon solvent through a packed bed of a cationic exchange resin catalyst containing acid groups, in a reaction zone, said reaction zone being maintained at a pressure from about 1 to about 20 atmospheres and at a temperature from about 120.degree. C to about 160.degree. C.

    摘要： Metal salts and amides of alkyl-lactam acetic acids are prepared by reacting gamma-hydrocarbyl butyrolactone acetic acid compounds derived from alkenylsuccinic anhydrides with metal compounds and amines or amines alone. High molecular weight lactam acid salts and amides and metal complexes and metal carbamates thereof are useful as detergents or dispersants in organic industrial fluids. Another aspect of this invention is a method of preparing lactone acetic acids in yields up to 90% conversion from alkenylsuccinic anhydrides.

    摘要： Certain water-soluble polymers retain their viscosities in high brine environments and are highly useful as surfactant-mobility control agents in oil recovery processes. These polymers have stiff backbone chains which are poly-2,6-dimethyl-p-phenylene oxide, polysulfone or poly(p-phenylene ether-sulfone) and side chains which may be formed by halomethylating phenyl rings of these backbone chains followed by quaternizing the halomethyl groups. For more thickening power, the molecular weight of the polymer can be increased by controlled cross-linking with a calculated amount of difunctional amine.
