Synthesis and characterization of poly(hydroxyamide-benzoxazole) multi-block copolymers

Poly(hydroxyamide-benzoxazole) multi-block copolymers were prepared from the polymerization of 2,2'-bis(3-amino-4-hydroxyphenyl)-hexafluoropropane (6FAP) and 4,4'-oxydibenzoyl chloride (ODBC). N,O-bis(trimethylsilyl) trifluoroacetamide (BSTFA) or N,O-bis(trimethylsilyl)acetamide (BSA) was used as a silylation agent to activate amine functional groups. The amine terminated hydroxyamide prepolymers (ATHA) were synthesized by employing the low temperature solution polymerization via the in situ silylation method. p-Toluenesulfonic acid was added into the reaction mixture of ATHA, which in turn followed by cyclodehydration at 150 ～ 190°C 4 for 24 hrs to produce amine terminated benzoxazole oligomers (ATBO). Finally, the poly(hydroxyamide-benzoxazole) multi-block copolymers were prepared from the condensation of ATHA, ATBO and ODBC by employing the silylation method at relatively low temperature of 60°C. In the present work, properties of multi-block copolymers have been investigated.

Synthesis of multiwalled carbon nanotube/fluorine-containing poly(p-phenylene benzoxazole) composites exhibiting greatly enhanced dielectric constants

A series of high-performance polymer/carbon nanotube (CNT) composites with different nanotube contents have been prepared via condensation of N-silylated diamino terminated precursor of the polymer with acid chloride-functionalized CNTs and subsequent thermal cyclodehydration. The composites have been fully characterized by infrared and Raman spectroscopy, electron microscopy, and thermal analysis. Various interesting morphologic features including helical structures have been observed in the composites as a result of covalent attachment of the polymer. The composites exhibit excellent thermal stability and a significant improvement in the dielectric constant and mechanical strength with the inclusion of CNTs. Copyright
