Abstract

Abstract:

The miscibility of PVC/PBD-b-PMMA blends has been studied. The results of DMA and TEM reveal that PBD-b-PMMA and PVC are partially miscible. The miscibility depends on the composition of the blends, the molecular weight of the component polymers, and the proportion of PBD and PMMA in the block copolymers. The miscibility of PVC-5 with the copolymers is better than that of PVC-3 and PVC-7. When the proportion of PBD and PMMA are almost equal, the miscibility increases with the molecular weight of PBD-b-PMMA.

Key words: PVC, PBD-b-PMMA, Blends, Miscibility, Morphology
