It is obvious that asymmetric T g vs composition curves of random copolymers cannot be adapted by the Gordon-Taylor equation based on volume additivity, even if instead of the model-specific additivity parameter K G-T = ( ρ 1 / ρ 2 )( Δα 2 / Δα

Glass transition temperatures T g for a wide variety of (A-random-B) copolymers have been determined by means of d.s.c., with A, B = methyl acrylate, ethyl acrylate, n-butyl acrylate, iso-butyl acrylate, t-butyl acrylate, 2-ethyl hexylacrylate, methy

The influence of reducing gases on the electrical conductivity or gas sensitivity of thin-film tin oxide sensors is investigated as a function of the tin oxide film thickness and the concentration of palladium. Examinations of the temperature depende

The paper describes a new calorimetric measuring vessel for the commercial precision calorimetry system LKB 8700. The vessel was tested by measuring the enthalpy of solution of CaF 2 in water and the enthalpies of immersion of different minerals in w

Copolymers of butylmethacrylate and of methylmethacrylate with donor N-(2-hydroxyethyl)carbazolyl methacrylate and acceptor methacryloyl-β-hydroxyethyl-3,5-dinitrobenzoate respectively, exhibit specific glass transition behaviour. The copolymers wit

SUMMARY Copolymers of methyl methacrylate and of butyl methacrylate with N-(2-hydroxyethyl)carbazolyl methacrylate and with methacryloylB-hydroxyethyl-3,5-dinitrobenzoate, respectively, as charge transfer complexing agents have been prepared. Despite
