Synthesis and characterization of poly/organo-montmorillonite composites

The incorporation of clay nanoplatelets into biodegradable polymers is considered to be one of the best combinations for developing environmentally-benign high-performance materials. We utilized organo-montmorillonite (OMMT) in ring-opening polymerization of bisphenol A diglycidyl ether and adipic acid to prepare biodegradable linear poly(bisphenol A diglycidyl adipate)/organo-montmorillonite (PBA/OMMT) nanocomposites. The products were analyzed by XRD, TEM, 1H NMR, GPC, DSC and TGA. The results demonstrated that PBA/OMMT nanocomposites were successfully formed and sufficient for the ordinary heating process. OMMT was beneficial for the modification of PBA hydroxyl polyesters on branched rate and polydispersity.
