摘要： A novel partial ester of cellulose with a nitrogenous carboxylic acid, the ester being useful as an antibacterial agent, a flame retardant, etc.; and a simple process for producing the partial ester. Fibers made of the partial ester have washing-resistant antibacterial properties and flame retardancy. The process comprises contacting a nitrogenous carboxylic acid ester with cellulose and heating the mixture.

摘要： A method is described for the chemical modification of pre-shaped hydrogels in non-aqueous medium. The conditions permit the reaction of highly expanded, porous hydrogel particles, such as spherical beads, using pseudo homogeneous reaction conditions in the absence of water. The method involves a three step procedure in which the porous gels are solvent exchanged into a water-free solvent (step 1) with minimal change in gel dimension and porosity; followed by reaction under non-aqueous condition (step 2); and followed by solvent exchange into water (step 3). Many different types of reactions requiring non-aqueous conditions may be carried out using these conditions. The method has particularly been demonstrated for crosslinking fluorinating beads, and for esterifying beads in a reaction involving multifunctional free carboxylic acids in the presence of dicyclohexylcarbodiimide (DCC).

摘要： The invention relates to a method of treating chemical pulp fibers by a polymerizing hydroxy acid, the fibers thus obtained and the products refined from them. In the method, the hydroxy acid reacts with the reactive groups of the fibers in the presence of a catalyst, forming ester bonds. The following units of the same hydroxy acid are oligomerized and/or polymerized to these grafted acid residues. The fibers thus treated and the products refined thereof endure better processing stages that include drawing and stretching than untreated fibers.
