説明
To obtain biodegradable functional polymers, the molecular weights of highly dicarboxylated polysaccharides were reduced sufficiently to make possible their assimilation by environmental microbes. Dicarboxylated polysaccharides reduced in molecular weight were prepared by thermal hydrolytic cleavage of high molecular weight dicarboxylated pectic acid, amylose and amylopectin. Biodegradability and builder performance of the dicarboxylated polysaccharides showed inverse tendencies with increase in molecular weight. Molecular weight for optimum biodegradability and functionality as a builder for detergents was between 1500 and 2000. Among the dicarboxylated polysaccharides examined, dicarboxypectic acid was found to have the greatest detergency.
