ABSTRACT:
Disclosed is an emulsified alkenylsuccinic acid sizing agent useful for acid papermaking. The sizing agent has a solid concentration of at least 25% by weight and comprises an alkenylsuccinic acid which is the reaction product of a branched internal olefin and maleic anhydride and which has been dispersed in water by an emulsifying and dispersing agent comprising polyvinyl alcohol. The sizing agent results in good storage stability and has an excellent sizing effect at a low addition ratio immediately after completion of high-temperature papermaking and over a wide pH range.
