Semicrystalline Macromolecular Design by Nitroxide-Mediated Polymerization

Abstract

The syntheses of PODA-b-PMA and PODA-grad-PMA copolymers using NMP are reported for the first time. The gradient copolymerization of ODA and MA was performed in a semi-batch system with a continuous addition of MA during ODA polymerization. The results showed that the semi-batch NMP proceeded in a living fashion, producing well-defined copolymers with narrow polydispersities and controlled molecular weights. The potentially semicrystalline copolymers were characterized by techniques such as H-1 NMR, SEC and DSC. Their surface crystallization has also been studied by AFM.
