Stabilization of poly(vinylene‐arsine)s (1) towards silver nanoparticles was carried out to estimate the coordination and protecting ability of phenyl‐substituted poly(vinylene‐arsine) (1a) and methyl‐substituted poly(vinylene‐arsine) (1b). In the presence of 1 in 1:1 ratio with AgNO3, colloidal solutions were obtained. The methyl‐substituted poly(vinylene‐arsine) (1b) is a better stabilizer for silver...
Radical reaction of bis(4-prop-2-ynyloxyphenyl) disulfide (1) with 2,2′-azobis(isobutyronitrile) as an initiator provided a polymer with dithioalkene units (2). The 1H and 13C NMR spectra of 2 showed that 2 had mainly E-form dithioalkene structure. The radical reactions of 1 and diphenyl diselenide (3) or diphenyl ditelluride (5) were also carried out. At higher temperature than 70 °C, polymers were...
Summary Cross-linked poly(vinylene-arsine)s (4) were synthesized by a free-radical terpolymerization of phenylacetylene (2), hexaphenylcyclohexaarsine (l), and p- or m-diethynylbenzene (p- or m-3) at different compositions in the presence of a catalytic amount of AIBN. The number-average molecular weights of the resulting polymers were a few thousands estimated by gel permeation chromatography (GPC)...
