Abstract

The coefficients of diffusion of hydrocarbons and the rotation frequencies of spin probes plasticized with oligovinyltrimethyl silane ( M=600) have been measured. Plasticization results in a monotonic reduction in the glass transition temperature from 170 to 60° for a sample containing 43% of the oligomer. The general character dependences of the translational and rotational mobilities of various types of low molecular weight substances on the plasticizer concentration has been determined.
