Abstract
An internal sizing agent for paper making which produces excellent sizing effect and which can be used in neutral to alkaline regions without the ordinarily employed fixing agent such as aluminum sulfate. The sizing agent contains a specific reaction product and/or hydrogenation product of said reaction product, said reaction product being prepared by adding maleic anhydride to branched internal olefins having 14 to 36 carbon atoms which branched internal olefins are obtained by oligomerizing one member or a mixture of two or more of olefins having 6 to 18 carbon atoms.
