A novel biodegradable hyperbranched polyester prepared from cellulose and tyrosine via the synthesis route of glycopeptides†
Abstract
A novel cellulose-based hyperbranched polyester (CHBP) has been prepared through the polycondensation of an ABn-type monomer, which was synthesized from a reaction of acetylated oligomeric cellulose bromide with tyrosine via the Koenigs–Knorr reaction, followed by deacetylation. Its chemical structure, thermal stability as well as biodegradability were preliminarily investigated.
