Abstract
A new concept of a ‘Macromolecular Micro Composite’ is proposed as a melt processable and thermodynamically miscible blend of a flexible polymer and a quasi-rigid polymer in which the flexible polymer is molecularly reinforced by a quasi-rigid macromolecule offering synergistic properties and improved mechanical properties as compared to those of the constituent flexible polymer. Fundamentals are presented and the concept is established, herewith, by melt processing a miscible macromolecular micro composite of flexible polyetherimide reinforced by quasi rigid polyamide-imide with improved mechanical properties as compared to those of flexible polyether-imide. Advantages of macromolecular micro composites over molecular composites, self reinforced blends, and other molecularly reinforced polymer blends are discussed. 23 Refs.
