PROCESS FOR PREPARING AN EXFOLIATED, HIGH I.V. POLYMER NANOCOMPOSITE WITH AN OLIGOMER RESIN PRECURSOR AND AN ARTICLE PRODUCED THEREFROM

摘要

This invention is directed to a process for preparing an exfoliated, high I.V. polymer-platelet particle nanocomposite comprising the steps of: (i) melt mixing platelet particles with a matrix polymer-compatible oligomeric resin to form an oligomeric resin-platelet with a high molecular weight matric polymer, thereby increasing the molecular weight of the oligomeric resin-platelet particle composite and producting an exfoliated, high I.V. polymer nanocomposite material. The invention also is directed to a nanocomposite material producted by the process, producted produced from the nanocomposite material, and a nanocomposite prepared from an oligomeric resin-platelet particle precursor composite.
