We report measurements of the quantum efficiency and time decay of photoluminescence in the conjugated polymers poly(g phenylenevinylene) (PPV) and poly(Z-methoxy, 5-(2'ethyl-hexyloxy)-p-phenylenevinylene) (MEH-PPV). MEH-PPV is soluble and we measure values for the quantum yield for luminescence of
## Abstract The highβpressure meltβcrystallization behaviors of poly(__p__βphenylene sulfide) (PPS) were investigated using WAXD, DSC, TEM and SEM. PPS extendedβchain crystals with __c__βaxis thickness exceeding 4.5 Β΅m were formed at high pressure. The DSC results showed that the melting temperatur
