【Abstract】 A carboxylic derivative of a plant glucomannan, CMG, was prepared through chemical modification and the prospects for use as a novel strength additive in the papcrmaking industry were investigated. CMG with DS of 0.1- 0.3η of 600-900 (ml/ g) has a solution stability much better than those of the native material. The product has been used for kraftpapcr. typing-paper and cigarcttcpapcr for one year, and has been proved that the dry strength of the sheets increases markedly by adding CMG, for example, an increase over 25% of bursting strength and 20% of breaking length in an amount of 0.7% CMG based on the dried pulp. The product, as reported from the manufacturers, also possesses many other functions, such as beating, sizing, retaining and draining effects etc. CMG has been produced on a pilot plant scale.更多还原
