The emulsion is an oil-in-water emulsion of alkenyl succinic anhydride emulsified with a polymer comprising at least one primary or secondary amine containing monomer. The method comprises adding an oil-in-water emulsion to the papermaking process; wherein the oil-in-water emulsion comprises alkenyl succinic anhydride emulsified with a polymer comprising at least one primary or secondary amine containing monomer; and wherein the oil-in-water emulsion is added in an amount sufficient to improve sizing of the paper produced by the papermaking process. The primary or secondary amine may be a secondary amine comprising diallylamine, and the polymer may be a diallylamine-acrylamide copolymer.

摘要： The invention is directed towards methods and compositions for improving the sizing of paper using PAE. Proper sizing of paper requires that a sizing agent adequately disperse so as to evenly distribute on the paper. Proper sizing also requires that the agent not cause runnability or chemical problems with other materials or equipment used in the papermaking process. PAE displays unexpected attributes that allow it to disperse sizing agents. Best of all it is not subject to the same overdose effect of typical emulsifiers such as cationic starch. As a result PAE is an excellent option for use in sizing paper.
摘要翻译：本发明涉及用于改进使用PAE的纸张尺寸的方法和组合物。适当调整纸张尺寸需要施胶剂充分分散，以均匀分布在纸张上。适当的尺寸也要求该代理不会造成造纸过程中使用的其他材料或设备的运行性能或化学问题。 PAE显示意外的属性，允许它分散尺寸代理。最重要的是不会像典型的乳化剂如阳离子淀粉那样过量的效果。因此，PAE是用于尺寸纸张的绝佳选择。

摘要： Paper is made by providing an anionic aqueous emulsion of a size, usually a reactive anhydride size, and mixing it into a cellulosic suspension prior to drainage of the suspension to form a sheet which is then dried to provide paper (including paper board). The emulsion is preferably stabilised wholly or mainly by 0.5 to 30 parts by weight (per part by weight size) of water soluble, anionic, polymeric stabiliser, which is preferably anionic starch. Alternatively, the emulsion may be added to the cellulosic suspension while it is anionic, before mixing retention into it. The emulsion may be added to the cellulosic suspension after cationic retention aid has been added to it, the emulsion being added with, before or after mixing anionic microparticulate material or other anionic bridging aid, prior to drainage of the suspension.

摘要： The invention is a paper coating system which introduces ASA particles having sizes in the sub-micron region into an emulsifier without shearing the emulsifier. The system has a continuous output--as distinguished from a batch system. The system comprises a variable speed low pressure starch metering pump, a variable speed high pressure ASA metering pump, a high pressure atomizing nozzle assembly, and a manifold which brings the starch and the atomized ASA flow together. The high nozzle pressure breaks up or atomizes the ASA into minute sub-micron particles that are evenly distributed throughout the starch to form a nearly perfect oil in water emulsion. By controlling the nozzle pressure, the proper particle size can be produced quite easily. An optical monitoring device that uses a coherent (laser) light source continuously measures and validates the quality of the ASA emulsion.
