Coals of increasing rank contain a mixture of solid fragments and particles which look liquid. The first ones are a fractions insoluble in boiling anthracene-oil, the others are /I fractions (soluble in anthracene-oil but insoluble in toluene). The content of fi fraction passes by a maximum as softe

Two methods of obtaining electrically conductive fabrics by in situ polymerization of aniline were compared. Conductive fabrics were prepared by immersing the nylon 6 fabrics in 100% aniline or an aqueous hydrochloride solution of aniline followed by initiating successive polymerization in a separat
## Abstract Polypyrrole/polyethylene composite films were prepared by vapor phase polymerization of pyrrole on porous polyethylene films using iron(III) chloride as an oxidant. By drawing the films before or after the polymerization of pyrrole, anisotropy in electrical conduction was observed paral
