Poly(2,6-dimethyl-1,4 -phenylene oxide) (PPO) is a chemically resistant polymer and, therefore, an attractive material for the formation of membranes. However, membranes of unmodified PPO prepared by an immersion precipitation possess very low hydraulic permeabilities at the filtration processes. T
The thermal oxidation and photo-oxidation of poly(2,6-dimethyl-l,4phenylene oxide) have been examined. Oxidation of the plastic results in the evolution of carbon dioxide, nitrogen and traces of hydrogen, the introduction of considerable crosslinking, and increased absorption in the hydroxyl and car
The thermal degradation and kinetics of poly(2,6-dimethylphenylene oxide) (PPO) were studied by high-resolution thermogravimetry. The thermogravimetry measurements were conducted at an initial heating rate of 50°C min Ϫ1 , resolution 4.0, and sensitivity 1.0 in both nitrogen and air from room temper
## Abstract Blends of styrene–butadiene–styrene (SBS) or styrene–ethylene/1‐butene–styrene (SEBS) triblock copolymers with a commercial mixture of polystyrene (PS) and poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO) were prepared in the melt at different temperatures according to the chemical kind of
