The molecular dynamics of p-phenylene vinylene (PPV) oligomers, synthesised by a condensation reaction and separated by molecular distillation, have been investigated using the electrooptic Kerr effect. The experimental Kerr constants of these materials change sign from positive to negative in going
## Abstract Poly(__p__βphenylene sulfide) (PPS) oligomers were synthesized from sodium sulfide (SS) and pβdichlorobenzene (__p__βDCB) in hexamethylphosphoramide (HMPA) under atmospheric pressure. The effects of reaction time, temperature, and monomer ratio on end groups and molecular weight of PPS
