摘要： A new class of polymeric additives for papermaking is disclosed as well as a process for their manufacture, a method for their use and a paper sheet containing the addition.. The additives can be used in paper manufacture as agents for improving retention, paper machine operation and the strength properties of the product. The additives are manufactured from the biomass that is a by-product of microbiological production of citric acid by a fermentation process using Aspergillus Niger, suitable by-product from other microbiological process, or from a biomass specifically produced for this purpose. The biomass that contains acetyl amino groups or other amides is chemically modified by hydrolysis of the amides to form primary amino groups. Under neutral or acidic conditions these primary amines become cationic, which assures a good absorption of the additive onto fibres and fines of pulp that is generally of anionic nature. Furthermore, primary amino groups can form chemical bonds with carbonyl groups, and ionic interactions with carboxyl groups. Both these groups are abundant in the fibres and fines of pulps, especially in mechanical pulps. The additive prepared in this manner might contain glucosamine polymers that might be chemically bound to a carbohydrate polymer or oligomer. Novel papermaking additives produced in this manner are particularly suitable for the production of paper from fibrous pulp suspensions produced at least partially from mechanical pulps, the high negative charge of which tends to overwhelm a majority of conventional cationic polymers.
摘要翻译：公开了一类新型的造纸用聚合物添加剂及其制造方法，其使用方法和含有该添加剂的纸张。添加剂可用于造纸作为改善保留剂，造纸机操作的试剂和产品的强度性能。添加剂由生物质制成，生物质是通过使用黑曲霉的发酵方法生产柠檬酸的副产物，其他微生物过程的合适的副产物或由此产生的生物质。含有乙酰氨基或其它酰胺的生物质通过酰胺水解而化学修饰形成伯氨基。在中性或酸性条件下，这些伯胺是阳离子的，这确保了添加剂对通常具有阴离子性质的纸浆的纤维和细粉的良好吸收。此外，伯氨基可与羰基形成化学键，并与羧基形成离子相互作用。这两个组在纸浆的纤维和细粉中都是丰富的，特别是在机械纸浆中。以这种方式制备的添加剂可能含有可能与碳水化合物聚合物或低聚物化学结合的葡糖胺聚合物。以这种方式生产的新型造纸添加剂特别适用于从至少部分由机械纸浆生产的纤维纸浆悬浮液生产纸张，其高负电荷倾向于压倒大多数常规阳离子聚合物。

摘要： Processes for preparing water-soluble papermaking polymer additives having a multitude of free amino groups effective to form cationically charged complexes with components of a pulp suspension are described, comprising: reacting ammonia and epichlorohydrin (ECH) with ammonia in excess to yield a starburst polymer with a molecular weight of 3000-10 6 ; reacting ECH and ammonia to produce tris(3-chloro-2-hydroxypropylamine) and reacting this with a diamine to yield a water-soluble branched polymer with a molecular weight of 3000-10 6 ; reacting polyepichlorohydrin with a variety of amines, a polyol or ammonia to yield linear polymers, cross-linked polymers and polyamines. The additives are used as agents for improving retention, drainage, product strength and paper machine operation in paper manufacture. Under neutral or acidic conditions these primary amino groups become cationic, which assures good adsorption of the polymer onto anionic fibres and fines used for production of paper or paperboard. By adsorbing on several fibres or fines, the polymer can increase the retention of fines and fillers. Primary amino groups of these polymers can also form chemical bonds with carbonyl groups of cellulose, lignin and hemicellulose, which are especially abundant in the fibres and fines of mechanical pulps. The cross-linking of fibres and fines by chemical bonds can increase the initial strength of wet web and the strength of rewetted paper.
