Synthesis for poly(phenylene oxide) polymer and its sulfonation Huang, R.Y.M.; Kim, J.J.

Poly(phenyleneoxide) has good thermal and chemical stability. Sulfamide acid, one of the sulfonic acid derivatives, involves both an electron-drawing carbonyl group and a conjugated structure. In this paper, we focused on the synthesis of poly(2-methyl-6-sulfamide-1,4-phenyleneoxide) bearing sulfamide acid and the properties including proton conductivity and thermal stability. We also evaluated the conductivity of phosphonated poly(phenyleneoxide) and sulfonated poly(phenylenesulfide).

Poly(phenylene oxide) Thermoplastic Resins - …

A new poly(phenylene-co-dialkoxyphenylene) derivative was synthesized by the Suzuki coupling of aromatic bromoboronic acids. This showed strong violet photoluminescence (peak 415 nm) in the solid state and good solubility in organic solvents. A multilayer light-emitting diode was constructed with the structure indium-tin oxide/poly(p-phenylenevinylene)/polyphenylene calcium. Efficient light emission was observed with a peak maximum in the blue region of the visible spectrum.

Linear polyphenylene sulfide has been synthesized by ..

The blends offer superior processibility compared to pure PPOs. Their viscosities are lower. A range of properties can be obtained depending on the ratios of PPO and PS. Blends with nylons (PA 6/6) offer improved chemical resistance and perform well at high temperatures. The water absorption is low and the molded products have excellent dimensional stability.

poly(phenylene oxide) information and properties

AB - Novel pH-sensitive gel-forming pentablock copolymers based on commercially available Pluronic (poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide), PEO-b-PPO-b-PEO) triblock copolymers and cationic diblock copolymers based on polyethylene glycol) methyl ether (PEGME) were synthesized by oxyanionic polymerization. Polymerization of the cationic moiety, poly((diethylamino)-ethyl methacrylate), PDEAEM, was initiated by a difunctional potassium alcoholate of the triblock Pluronic copolymer F127 (PEO106-PPO69-PEO106) or PEGME. The difunctionality of the initiation using the triblock macroinitiator, indicating formation of a pentablock copolymer rather than a tetrablock copolymer, was verified by functionalized termination of the living polymer chains. Critical micellization temperatures (cmt) of the synthesized polymers were obtained from differential scanning calorimetry for the pentablock materials. The pentablock copolymers retained the thermoreversible gel-forming properties of Pluronic F127 as well as similar cmt values. The polydispersity of both the diblock and pentablock copolymers was similar to the macroinitiators, indicating a very low polydispersity associated with the addition of the cationic PDEAEM blocks. Both of the materials show pH-sensitive release behavior, whereas the native polymers do not.

Nanocomposites of polyphenylene oxide ..

Modified polyphenylene oxide materials are actually blends of PPO and polystyrene. Different combinations of each, along with possible additive packages, make it possible to produce materials with a wide range of physical and mechanical properties, heat resistance, and flame retardancy. Compounds are available with heat distortion temperatures from 170 to 460 degrees F (77 to 238 degrees C) and with a flammability ranges from UL94HB to V-0.
