Abstract

Des aspects de la présente invention comprennent des compositions et des méthodes de production d'une résine nanocomposite polymère-polysaccharide, comprenant la polymérisation d'un monomère d'alcane diol et d'un monomère d'agent diacide alcane dans un mélange comprenant des nanocristaux de polysaccharide dispersés, un catalyseur et un ou plusieurs additifs facultatifs dans des conditions suffisantes pour produire une résine nanocomposite polymère-polysaccharide. Des aspects de la présente invention comprennent en outre des compositions et des méthodes de production d'un nanocomposite de succinate de polybutylène, comprenant la dispersion de nanocristaux de cellulose dans du 1,4 butanediol (BDO) pour former une dispersion de cellulose-BDO et l'estérification de la dispersion de cellulose-BDO et d'anhydride succinate pour former une pluralité d'oligomères de succinate de polybutylène. Les oligomères de succinate de polybutylène sont condensés pour former un nanocomposite de succinate de polybutylène.
