Claim 0:
1. A method for producing a polymer-polysaccharide nanocomposite resin, the method comprising the steps of:
a) preparing and heating a mixture comprising a diacid agent monomer and a diol monomer at a first temperature to esterify the diacid and diol monomers;
b) contacting the heated mixture of step a) with a nanocellulose crystal (NCC) dispersion after esterification of the monomers to produce a NCC oligomeric composition; and
c) heating a second mixture comprising the NCC oligomeric composition and a catalyst at a second temperature and under reduced pressure of 500 mTorr or less to polycondense the NCC oligomeric composition and produce a polymer-cellulose nanocomposite resin.
