Abstract
Crystallization of polydimethylsiloxane (PDMS) filled with insulating carbo n has been studied in an inhomogeneous temperature field. It is shown that the material polarization during the melt-crystal transitions depends on th e concentration of the filler. This results in a decrease of the temperatur e coefficient of polarization with the concentration of dielectric carbon. The temperature dependences of thermodynamic functions are calculated for t he crystallization range of the crystals under study. (C) 2000 MAIK "Nauka/ Interperiodica".
