Copolymers containing polybenzoxazole, polybensothiazole and polybenzimidazole moieties |
| abstract |
ABSTRACT Block copolymers can be formed from hetero-cyclic polymers such as PBO and thermoplastic polymers such as polyamide or poly(aromatic ether ketone). The block copolymer compositions are thermoplastic and do not experience substantial phase separation, even at about their glass transition temperature. The block copolymer compositions can be formed into fibers, films and laminate or compression-molded articles. PBO, PBI and PBT polymers terminated by active aromatic rings or acylating groups are particularly useful for making the block copolymers. |
