    摘要: A polymer comprising as part of its polymer backbone a cineole-type moiety having a structure according to Formula (II): where one of R6 to R10 represents A-O— and one of R6 to R10 represents —O—B and the remainder of R6 to R10 represent H, where A and B, which may be the same or different, represent the remainder of the polymer backbone and are independently selected from the group consisting of polyurethane, polyester, polyamide, polycarbonate, polyimide, polyether, polyepoxy, polyacrylate, polysiloxane, polyvinyl and combinations thereof. The polymer comprising as part of its polymer backbone a moiety of Formula (II) or polymer blend, comprising this polymer, can be used for production of a sheet, fiber or film.
