The nanocomposites of Multiwall carbon nanotubes (MWNTs) and poly(arylene sulfide sulfone) (PASS) were prepared via in situ polymerization. The compounds were found to distribute uniformly and had excellent thermal properties with glass transition temperatures (T(g)) of 222-224 degrees C and initial degradation temperature (T(d)) of 437.7-445 degrees C. They had better solubility and could dissolve in strong aprotic solvents such as N-methyl-2-pyrrolidone (NMP), dimethylformamide (DMF), dimethyl sulfoxide (DMSO) and so on. After acidification and fluobenzene-functionalization treatment, the MWNTs and polymer matrix via in situ polymerziation showed better compatibility than the composite mixing directly. Additionally, the composites prepared via in situ polymerization had good electrical conductivity of 10(14)-10(7.6) omega x m and mechanical properties with Young's modulus of 0.63-1.08 GPa.

“…Many engineering thermoplastics with excellent physicochemical properties have been developed for many industrial applications [1] . Polymers containing sulphur atoms, for example poly(phenylene sulfide) (PPS), poly-(phenylene sulfide-sulfone) (PPSS), poly(phenylenesulfide-ketone) (PPSK), poly(phenylene sulfide-amide) (PPSA), poly(phenylene sulfide-ketone-ketone) (PPSKK) and poly(ether-sulfone) (PES) have attracted attention as high performance polymers and used as engineering plastics [2] due to their excellent thermomechanical properties.…”

Ether-sulfonate copolymer of 1,1 0 -bis(4-hydroxyphenyl) cyclohexane, bisphenol-A and 4,4 0 -disulfonyl chloride diphenyl ether [PESAC] has been synthesized and characterized by IR, 1 H NMR, viscosity ([g] ¼ 0.23-0.25 gdl À1 ), density (1.3172 g/cm 3 ), tensile strength (11.8 MPa), electric strength (64 kV/mm), volume resistivity (4.24 Â 10 14 X cm) and dielectric constant (1.0). PESAC possesses excellent solubility, good hydrolytic stability against water, acids, alkalis and salt, high T g (170 C) and high thermal stability (290 C). The associated kinetic parameters namely energy of activation E (386.6 kJ mol À1 ), order of the reaction n (3.1), frequency factor A (1.53 Â 10 31 s À1 ) and entropy change DS Ã (346.1 kJ mol À1 ) have been determined and discussed.

A comparative study of the influence of 2-(10-oxo-10H-9-oxa-101 5 -phosphaphenanthrene-10-yl)-benzene-1,4-diol (DOPO-HQ) and 2-(2,8-dimethyl-10-oxo-10H-101 5 -phenoxaphosphine-10-yl)-benzene-1,4-diol (DPPO-HQ) on their ability to form polysulfones (PSU) with 4,4 1 -difluorodiphenylsulfone (DFDPS) as well as the properties of the aromatic phosphorus-containing polysulfones (P-PSU) is reported. These properties are also compared to bisphenol A-based polysulfone. Both diols have the phosphorus unit as substituent and differ in the number of oxygen atoms within the environment of the phosphorus changing from DOPO-HQ (phosphinate structure, Ar 2 OP(=O)) to DPPO-HQ (phosphine oxide structure, Ar 3 PO). The nucleophilic aromatic polycondensation was carried out successfully using both phosphorus-containing aromatic diols instead of bisphenol A and was followed by ATR-FTIR in-line monitoring. The use of DPPO-HQ decreased the number of side reactions and enhanced slightly the molecular weight. The thermal stability of DPPO-HQ-based PSU is slightly better than DOPO-HQ-based PSU. Thermal decomposition schemes for PSU and for both P-PSUs are proposed based on thermogravimetric analysis and Pyrolysis GC-MS results.
