Full Description:
This application is a continuation of application Ser. No. 859,142, filed May 2, 1986 now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     The present invention relates to a sizing agent for use in cellulosic paper-making. 
     Heretofore a wide variety of sizing agents for use in paper-making have been proposed such as rosin-based, wax-based, alkylketene dimer based, polymer based, alkenylsuccinic anhydride based ones and the like and they have all been actually employed commercially. Since many of these conventional sizing agents are inherently water-insoluble, it is impossible to use them along as such so it is usually necessary to disperse and/or emulsify them in water with the aid of an emulsifying agent. However, the emulsifying operation has such drawbacks that it is only achieved with difficulty and that said operation requires additional costs therefor. 
     The alkenylsuccinic anhydride based sizing agents in particular undergo hydrolysis with time due to their inherent nature if they are kept in contact with water for a short period of time, thereby losing their sizing effect. 
     Due to the poor stability in water of said alkenylsuccinic anhydrides based sizing agents, they have the serious limitation that the sizing treatment should be finished in a short period of time and this has been the greatest drawback for applying them commercially, in spite of such excellent effects that they exert adequate sizing effect in lower concentrations, thus providing greater economical benefits as compared to that of rosin based, alkenylketene dimer based, wax based sizing agents and the like. 
     The inventor has carried out a wide variety of investigations on the sizing effect of alkenylsuccinic acids and their derivatives having various structures, and as a result he has found that unsaturated hydrocarbyl partial esters of alkenylsuccinic acids and the salts thereof are at least self-emulsifiable with water and provide an excellent sizing effect. 
     For example, unsaturated hydrocarbyl diesters of alkenylsuccinic acids not only entail significant difficulties in their synthesis but they also require troublesome procedures for emulsifying similar to conventional sizing agents and further they require additional auxiliaries such as an activator. In addition, they are inferior to unsaturated monohydrocarbyl esters in sizing effect, which makes them useless commercially. 
     Further, saturated partial(mono)- and di- hydrocarbyl esters of alkenylsuccinic acids have substantially no sizing effect, thus they cannot be used as a sizing agent. This is due to the fact that saturated hydrocarbyl mono- and di-esters of alkenylsuccinic acids are not substantially absorbed by paper and also they can only impart poor repellancy to paper. Contrary to the saturated hydrocarbyl mono- or di-esters, alkenylsuccinic anhydrides per se are readily absorbed by paper and make the resultant paper water repellent thereby exhibiting a sizing effect. However, once the anhydrides have been hydrolyzed to the corresponding dicarboxylic acids, the resulting dicarboxylic acids are not readily absorbed, thus losing their sizing effect. In this way, alkenylsuccinic anhydrides have drawbacks in that they drastically change their identity in water with time, thereby requiring a adequate care. 
     He has also found that if unsaturated hydrocarbyl partial esters of alkenylsuccinic acids or the water-soluble salt thereof are employed in combination with an acid catalyst, a further improved sizing effect can be obtained. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a sizing agent which is at least self-emulsifiable and stable in water for a long period of time and which is effective in lower concentration. 
     Another object of the present invention is to provide a sizing agent which can be prepared without any difficulties. 
     Further objects of the present invention will become apparent from the descriptions hereinafter referred to. 
     Thus, the present invention relates to a sizing agent for use in paper-making comprising at least one unsaturated hydrocarbyl partial ester of alkenylsuccinic acid of the general formula: ##STR1## wherein R represents an unsaturated hydrocarbyl group having at least six carbon atoms and R&#39; represents an unsaturated hydrocarbyl group having 3 to 18 carbon atoms, and a water-soluble salt thereof as an active component. 
     The present invention further relates to a sizing agent comprising at least one unsaturated hydrocarbyl partial ester of alkenylsuccinic acid set forth above and/or at least one water-soluble salt thereof together with at least one acid catalyst. 
     DETAILED DESCRIPTION OF THE INVENTION 
     It was generally known that compounds having an unsaturated group or groups are strongly absorbed by paper and render the paper more hydrophobic than saturated compounds. The sizing agent of the present invention supports the above fact. Therefore, in contrast to saturated esters of alkenylsuccinic acids which are only poorly absorbent by paper, thus having no sizing effect, unsaturated hydrocarbyl partial esters of alkenylsuccinic acids have surprisingly been found to be strongly absorbed by paper, making the paper significantly water-repellant, thereby providing an excellent sizing effect along with the advantages that they are not hydrolyzed by water, so that they can maintain their identity as a stable solution or dispersion in water for a long period of time. The unsaturated hydrocarbyl partial esters of alkenylsuccinic acids not only exhibit strong absorbability towards paper, but they also show no discoloring, and indicate a sustained stable sizing effect over a long period of time. Moreover, the unsaturated hydrocarbyl partial esters of the present invention provides consistently stable sized paper sheets even if said paper is treated with the agent in a low concentration. 
     The alkenylsuccinic anhydride or corresponding acid employed comprises all the alkenylsuccinic acid or anhydride in which the substituting side chain contains six or more than six carbon atoms and these include, for example, hexenyl-, octenyl-, decenyl-, octadecenyl-, dococenyl-, triancotenyl-, eicocenyl-succinic acid and the like and corresponding anhydrides. As the unsaturated alcohols, there may be mentioned all the unsaturated alcohols having 3 to 18 carbon atoms such as allyl-, propargyl-, butenyl-, butyn-, pentenyl-, hexenyl-, octenyl-, decenyl-, laurenyl-, oleyl-alcohols and the like. 
     The unsaturated partial esters of the present invention can be converted to water-soluble products or at least self-emulsifiable products by converting the remaining free carboxyl groups into a salt with alkaline metals or water-soluble amine whereby a stable aqueous solution or dispersion can be obtained by adding it to water. Upon use, it is preferably to use it with a cationic starch, as alkyleneoxide adduct based activator and the like as is conventionally employed in the art to fully assure the benefit of the sizing agent, although such use of an activator is not essential. 
     The unsaturated hydrocarbyl partial estersof alkenylsuccinic acids can be easily synthesized by a conventional esterification technique. Thus, an alkenylsuccinic anhydride or the corresponding acids and unsaturated alcohol are heated together to cause a reaction between them in the presence or absence of a catalyst through a ring opening in the case of anhydride, while in the case of acid through a dehydration to form an unsaturated partial ester. The ration between the acidic starting material to the unsaturated alcohol is such that the amount of the alcohol is sufficient to esterify only one of the carboxyl groups of the acid. 
     The unsaturated hydrocarbyl partial esters of alkenylsuccinic acids of the present invention may be added to paper material in an amount of 0.0001 to 10 parts by weight per 100 parts by weight of paper material (dry base) and preferably 0.01 to 2.0 parts by weight per 100 parts by weight of paper material. 
     The use of the above catalyst can significantly reduce the amount of unsaturated hydrocarbyl partial ester and thus provide great economical advantages. 
     Although this increase in the sizing effect achievable by the use of acid catalyst cannot be fully understood at present, the following assumption may be induced, although this should not be regarded as binding to any particular theory. An acid catalyst such as sulfonic acid, organic phosphoric acid, inorganic acid or Lewis acid excites the unsaturated linkage in the unsaturated hydrocarbyl partial esters, thereby bringing about a state where the double or triple unsaturated bond can be readily broken, so as to promote the etherification reaction with hydroxyl groups contained in cellulose or the esterification reaction by dehydration and that as a result the fixing of the sizing agent to paper is more fully effected in a short period of time. 
     As the acid catalyst, there may be mentioned sulfonic acid, organic phosphoric acid, inorganic acid, such as phosphoric acid, phosphorous acid, hypophosphorous acid, sulfuric acid, nitric acid, hydrochloric acid or the like, a Lewis acid such as boron fluoride, zinc chloride, aluminum chloride, ferric chloride and the like. These acid catalysts can be used alone or two or more in combination.
