Abstract: In this paper the preparation of polymer(PVC)-oligomer(HTBN) blends and their damping properties, mechanical properties and morphological structures are presented. It isfound that (1) the damping properties of PVC—HTBN biends are better than that of PVC itself, (2) HTBN content in blends and acrylonitrile content in HTBN have noticeableeffects on the mechanical properties of the blends, and (3) morphologically the blends have cell structure in which two phases can exist with dim boundary.

Key words: Damping materials, Blends of polyvinYlchloride and hydroxyl-terminated, Copolymer of butadicne and acrylonitrile, Morphology
