    摘要： The present disclosure is concerned with a process for the preparation of carboxylate containing polyurethane and the polymers so produced. Hydroxyl bearing components are reacted with tri- or tetra-carboxylic acid monoanhydrides so as to incorporate free carboxyl groups into the component, a proportion of the carboxyl groups are neutralized to ionic salts and hydroxyl component is then reacted with polyisocyanates and simultaneously or subsequently with chain extending agents. The polymer may be obtained as a dispersion in water and the chain lengthening agent may be water, formaldehyde or water soluble amines or hydrazines.

    摘要： A process is described for the preparation of cellulose derivatives containing amino groups that involves reacting, in the presents of water as a reaction medium, alkali cellulose or alkali cellulose derivatives with reagents represented by the following formula, X—(CH2)n—NR1R2 in which: X is selected from the group consisting of chlorine, bromine, iodine and a sulfonic acid radical R′SO3, in which R′ is an aromatic radical or an aliphatic radical; n is at least 2; and R1 and R2 independently of each other are selected from the group consisting of aliphatic substituents, branched alkyl substituents, cyclic alkyl substituents, aryl substituents, aryl substituents substituted by heteroatoms, H, and R1 and R2 together form a ring with the nitrogen. In the process, the mole ratio of cellulose to water, of said reaction medium, is 1:5 to 1:40 mol water per mol of anhydroglucose unit (AGU). Amino functional cellulose derivatives prepared in accordance with the method of the present invention are useful in cosmetic formulations and aqueous paper treatment compositions.
