A polystyrene–polyisoprene (PS–PI) diblock copolymer (10,000–50,000 g/mol) and a matched PS&ndashPI–PS triblock (10,000–100,000–10,000 g/mol) were employed to study the effect of chain architecture on the rheological response of ordered block copolymer melts. Both samples adopt hexagonal microstructures with PS cylind…

The results of investigations of polarized Raman spectra in ZnSiF6⋅6H2O and NiSiF6⋅6D2O single crystals in the temperature range 2–300 K are presented. It is found that the crystals are orientationally ordered at low temperatures. The orientational disordering is described by a model in which the rotational motion of…

The internal friction and dynamic modulus in pure Cu with various purities were measured in the temperature range from 25 to 250 °C after deformation at room temperature. All the specimens showed a large decrease in modulus during primary recrystallization the temperatures of which were found to be about 30 K lower fo…

A new method is provided for the calculation of Raman intensities. Atomic polarizabilities are used as parameters to reproduce the experimental intensities. The method was applied to an MgF2 signal crystal. It is shown that the use of anisotropic atomic polarizabilities allows the simulation of both the cell polarizab…
