Abstract: A wet strength resin comprising a water-soluble copolymer of A) a half-acid, half-amide corresponding to the following general formula:
wherein R' is H, alkyl or alkenyl and R is a hydrocarbon chain containing a multiple bond capable of radical polymerization and B) at least one other ethylenically unsaturated monomer; a cellulosic fibrous web treated with such a resin; a cellulosic fibrous web bonded with a binder comprising a copolymer latex of a monomer which is a polymerizable half-acid, half-amide corresponding to the following general formula:
wherein R is a hydrocarbon chain containing a multiple bond capable of radical polymerization and R' is H, alkyl or alkenyl, and at least one other ethylenically unsaturated monomer; and a papermaking process comprising the step of re- pulping such a cellulosic fibrous web.Abstract translation: 一种湿强度树脂，其包含A）与下列通式相应的半酸，半酰胺的水溶性共聚物：其中R 1为H，烷基或 烯基和R是含有能够自由基聚合的多重键的烃链，和B）至少一种其它烯属不饱和单体; 用这种树脂处理的纤维素纤维网; 与粘合剂结合的纤维素纤维网，所述粘合剂包含单体的共聚物胶乳，所述单体是可聚合半酸，对应于以下通式的半酰胺：其中R是烃 含有能够自由基聚合的多重键的链，R 1是H，烷基或烯基，和至少一种其它烯属不饱和单体; 以及造纸方法，其包括重新制浆这种纤维素纤维网的步骤。

Abstract: Cellulosic fibers, characterized by a lack of swellability and incapable of natural fiber-to-fiber bonding, are produced by a process which comprises treating an aqueous slurry of the fibers with a formaldehyde-free polymeric compound, heating the treated fibers to cause the polymeric compound to react with the fibers, and refiberizing to separate individual, treated fibers. The fibers are useful in the preparation of improved cellulosic webs characterized primarily by their increased bulk and improved softness.
