A liquid alkenyl succinic anhydride composition having superior paper sizing properties comprises: (A) the reaction product of maleic anhydride and straight chain alpha olefins in the C13 to C18 range; and (B) the reaction product of maleic anhydride and straight chain internal olefins or branched chain olefins in the C14 to C22 range, component (B) having a molecular weight which is at least 10 units higher than component (A). The composition can be used for the sizing of paper of for imparting water-repellency to cellulosic fabrics. The composition can be produced from maleic anhydride and a mixture of straight chain alpha olefins in the C13 to C22 range by separating the alpha olefins into a lower boiling fraction and a higher boiling fraction, isomerizing the higher boiling fraction, and either recombining the two fractions and reacting them with maleic anhydride, or independently reacting them with maleic anhydride and then combining the reaction products. c |
