## Abstract Electron donor and acceptor substituted poly(2โmethoxyโ5โmethylsulfinylโ1,4โphenylenevinylene) (PMMSPV) and a series of copolymers containing 1,4โphenylenevinylene (PV) units were synthesized via the waterโsoluble precursor pathway and cast into films. The electrical conductivity of FeC
The unperturbed chain dimensions K, of polydimethylstyrene (PDMS) in 12 solvents were determined b~ the Stockmayer-Fixman procedure. It was found that the value of K, decreased monotonously with increasing solvent power (i.e. with increasing the exponent a in the relation [r/] = K,I'd"l The unpertu
