## Abstract A facile synthesis of poly(phenylene sulfide) (PPS), poly(2βmethylphenylene sulfide) (PMPS), and poly(2,6βdimethylphenylene sulfide) (PDMPS) from the respective copper (I) bromothiophenoxides is described. Polymerization was effected in a 10:1 quinoline:pyridine mixture at atmospheric p
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
