The discovery and implications of the existence of two kinds of ion pairs in solutions of carbanion salts is described. Also discussed are the factors controlling tight–loose ion pair equilibrium: the nature of the carbanion and its counterion, tem

Films of PEO and PEO blends were efficiently crosslinked by exposure to ultraviolet radiation with high-pressure mercury lamp. Photochemical crosslinking proceeded in the presence of photoinitiator such as benzophenone or pentaerythritol triacrylate.

Binding constants of alkali picrates to poly( ethylene oxide)-based networks were measured spectrophotometrically in dioxane at 25 and 40°C. The networks were synthesized from aliphatic tri- or tetrafunctional isocyanates and α,ω-diamino-poly-(eth

Styryldiphenylbismuth (SDB) has been copolymerized with vinylbenzylphosphonate ester (VBP) and methyl methacrylate (MMA) producing highly radiopaque copolymers and terpolymers. The phosphoryl ester groups were also converted to phosphonic acids and t

A series of trialkyl carbamates of the general formula HC(Ph NHCOOCnH2n+1)3 with n = 16, 18, 20 and 22 were synthesized from alkanols and tris(p-isocyanatophenyl)methane. The star-shaped compounds effectively depress the pour point of wax-containing

Previously we demonstrated the feasibility of using up to 24% triphenylbismuth (TPB) as a radiopaque, monomer-miscible additive for dental acrylic resins. In this study we examined the influence of TPB on thermomechanical properties of a representati
