Polyester polymer nanocomposites

Abstract

Aspects of the present disclosure include compositions of and methods for producing a polymer-polysaccharide nanocomposite resin, including preparing a dispersion comprising polysaccharide nanocrystals, an alkane diol monomer and an alkane diacid agent monomer; polycondensing the alkane diol monomer and the alkane diacid agent monomer in the dispersion to produce a polymer-polysaccharide nanocomposite resin. Aspects of the present disclosure further include compositions of and methods for producing a polybutylene succinate nanocomposite, including dispersing cellulose nanocrystals in 1,4 butanediol (BDO) to form a cellulose-BDO dispersion and esterifying the cellulose-BDO dispersion and succinate anhydride to form a plurality of polybutylene succinate oligomers. The polybutylene succinate oligomers are condensed to form a polybutylene succinate nanocomposite.
