The effect of deformation of plasticized polyvinyl chloride on molecular mobility

Abstract

It was shown that uniaxial deformation of polyvinyl chloride, plasticized with dibutyl phthalate retards the molecular mobility of the plasticizer, displacing the correlation time spectrum towards higher values and distorting its shape. Appreciable anisotropy of the motion of dibutyl phthalate molecules is not observed. The behaviour of the parameters of nuclear relaxation of the polymer under strain is explained by the assumption of the existence of a 3-dimensional network in plasticized PVC. © 1988.
