Abstract A new water‐soluble amphoteric copolymer (PAC) was synthesized and evaluated as a dispersion agent for cement particles. PAC was prepared from acrylamide and 2‐(3‐carboxyacryloyloxy)‐ N ‐(carboxymethyl)‐ N,N ‐dimethyl ethanaminium (CAC) through free‐radical polymerization. The structure of the prepared polyme…

The effect of primary α content on creep and creep crack growth behaviour of a near α-Ti alloy has been investigated at 600°C. The alloy was heat treated at different temperatures so as to obtain different volume fractions of equiaxed primary α in the range from 5 to 40%. Constant load creep tests were carried out at…

The dynamics of disclination defect lines in a nematic liquid crystal are measured experimentally and considered theoretically. An optical trap is used to deform the line, enabling the previously unexplored regime of large deformation to be accessed. The relaxation follows a linear decay at large amplitude, crossing o…

Thermodynamic properties, such as entropy among others, have been shown to correlate well with formula volume, thus permitting prediction of these properties on the basis of chemical formula and density alone, with no structural detail required. We here extend these studies to the thermoelastic property of isothermal…

Abstract Cellulose extracted from waste newspaper was methylated using dimethylsulfate to produce methylcellulose with degree of substitution of 1.46 ± 0.06. This material was characterized by FTIR and DSC. An aqueous dispersion of methylcellulose was used to produce mortars of Portland cement (CPV‐ARI). The results s…

Thermoanalytical investigations TGA/DTG/DSC of polyamide–imide enamel after thermal ageing have been presented. The lifetimes at 260, 270, 280, 290, 300 °C were determined. The thermograms of the enamels after attaining of their lifetimes much depend on the ageing temperature. The temperatures of 5% loss of mass that…

The article describes a modified method of polyaniline synthesis. The classical oxidizer—aqueous solution of hydrogen peroxide was replaced by different solid state hydrogen peroxide complexes, what helped keep constant temperature of the reaction mixture. The highest yield of the polymerization was obtained using ure…

PP/PS interpolymer foam was tested in the rod extrusion process while using chemical blowing agents (CBA) and carbon dioxide physical blowing agent (PBA), respectively. Foam density decreases as blowing agent level increases. After it dips to a minimum, the foam density curve goes up. Although both CBA and PBA show th…

The total synthesis of protoporphyrin IX and its disodium salt using a new alternative method to the classical MacDonald condensation is reported. The key step is the reaction of the new unsymmetrical diiodo dipyrrylmethane 1 with the known dipyrrylmethane 2 . Coupling of the two fragments leads directly to porphyrin…
