    摘要： The invention relates to the use of polyesters for increasing the surface tension and improving the hydrophilic behavior of hydrophobic surfaces, wherein said polyesters are obtainable by polymerization of a) one or more unsulfonated aromatic dicarboxylic acids and/or salts thereof and/or anhydrides thereof and/or esters thereof, and b) ethylene glycol, c) 1,2-propylene glycol, and d) one or more polyalkylene glycols, and e) one or more compounds of formula (1) R1O(CHR2CHR3O)nH  (1) where R1 is a linear or branched, saturated or unsaturated alkyl group of 1 to 22 carbon atoms, preferably methyl, R2 and R3 are each independently hydrogen or an alkyl group of 1 to 4 carbon atoms, preferably hydrogen and/or methyl, and n is from 1 to 50, f) in the presence or absence of one or more crosslinking compounds having 3 to 6 functions capable of polycondensation, especially acid, alcohol or ester functions, with the proviso that said components d) are used in weight quantities

    摘要： A composition for sizing paper includes alkenylsuccinic anhydride (ASA) as the sizing agent and an emulsifier system of anionic emulsifiers and nonionic components, wherein the anionic emulsifiers are chosen from alkali metal salts of aliphatic carboxylic acids or aliphatic dicarboxylic acids and the nonionic components are chosen from polyethylene glycols.

    摘要： The disclosure relates to methods and compositions for enhancing the performance of a sizing agent in a papermaking process using a sizing agent enhancer. The sizing agent can be emulsified with an emulsifier and the sizing enhancer can be a polymer comprising at least one primary or secondary amine containing monomer. The method can comprise emulsifying the sizing agent with the emulsifier; and thereafter adding the emulsified sizing agent and the sizing enhancer, separately from or contemporaneously with the emulsified sizing agent, to a fiber furnish of a papermaking process. The combination of the emulsified sizing agent and the sizing enhancer improves the sizing of product paper over the use of the sizing agent without the sizing enhancer. In at least some embodiments, the emulsified sizing agent is ASA emulsified with a polymer comprising at least one primary or secondary amine containing monomer and the sizing enhancer comprises a diallylamine-acrylamide copolymer.
