    摘要: There is provided a strength resin polymer for papermaking that has pendant alpha-hydroxy acetal substituents to (N-alkyl)(C.sub.1-2 alkyl)acrylamide mer units. There also is provided a process for preparation of such resin polymer by adduction of a pre-existing polymer, or the monomer precursors thereto, with an acetal-aldehyde reactant under alkaline conditions. There is provided such strength resin polymer in the form of a fluid liquid system, for instance a fluid solution or a fluid oil-continuous water-in-oil emulsion, particularly when such a system has a high concentration of resin polymer. There is provided activated polymer versions of certain of such resin polymers and paper compositions containing such activated polymer. There is also provided papermaking processes including the step of activating such resin polymer.

    摘要: The invention provides a composition of matter useful for producing very soft high grades of tissue paper. The composition of matter comprises an adhesive composition that includes a glycerol-based polyol. The glycerol-based polyol prevents the composition from becoming brittle and is non-volatile. This allows the composition to become rewetted after creping and allows for strong levels of adhesion even at high temperatures.

    摘要: The invention provides a method of increasing the absorbency of an absorbent article. The method includes introducing a super-absorbent polymer composition to a paper web in a papermaking process to increase the absorbent capacity of an absorbent article made in the process. The polymer composition includes a super-absorbent polymer and a cross-linking agent applied to the paper web. The paper web is then subjected to heat in a heated drum or a through-air drier to cure or cross-link the super-absorbent polymer.
