An paper sizing composition which is suitable for use in neutral to alkaline paper making processes, which produces excellent sizing effect and which is well dispersed in water. Both the sizing effect and dispersion stability of the prepared sizing medium are durable. The paper sizing composition comprises: 20 to 90% by weight of (A) a reaction product and/or its hydrogenation product which reaction product is obtained by adding maleic anhydride to branched internal olefins having 14 to 36 carbon atoms which are obtained by oligomerizing one or a mixture of olefin starting materials having 6 to 18 carbon atoms and 10 to 80% by weight of (B) another reaction product and/or its hydrogenation product which reaction product is obtained by reacting maleic anhydride with straight chain internal olefins having 14 to 36 carbon atoms.
