摘要： 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.

摘要： An alkenylsuccinic anhydride type paper sizing agent composition which causes little contamination of a paper machine and exhibits an excellent sizing effect is provided.The paper sizing agent composition contains addition reaction products obtained from an addition reaction between a straight-chain internal olefin comprising 16 to 20 carbon atoms and maleic anhydride, any unreacted olefin and maleic anhydride having been removed from said addition reaction products; said addition reaction products comprising as a main component alkenylsuccinic anhydride (1:1 adduct) represented by formula (I): ##STR1## wherein both of R and R' are alkyl groups or either one of R and R' is an alkyl group while the other is a hydrogen atom; and a 1:2 adduct (2 moles maleic anhydride per mole of olefin), and a decarbonated product of said 1:2 adduct in a total amount, based on said addition reaction products, of from about 7 to about 12 mol%.

摘要： The present invention relates to a sizing agent which exerts excellent sizing efficiency even under severe conditions, namely, at an elevated temperature in the papermaking step, or at high conditions with a limited aluminum sulfate addition.The sizing agent for paper of the present invention is derived from i) dehydration condensation of an alkenylsuccinic anhydride and an organic carboxylic acid with a polyalkylene polyamine and ii) saponification of the remaining carboxyl groups with alkali following the dehydration condensation. More particularly, the present invention relates to a water-soluble sizing agent which is obtained by mixing an alkenylsuccinic anhydride with 1 to 20 times by molar equivalent, based on said alkenylsuccinic anhydride, as much as an organic carboxylic acid, adding 0.1 to 2.0 times by molar equivalent, based on said alkenylsuccinic anhydride, as much as a polyalkylene polyamine thereto so as to perform dehydration condensation. An then, to make the reacted material soluble to water, the remaining carboxyl groups are saponified with an alkali in an amount almost corresponding to the saponification equivalent.
