Mechanism of plasticizer evaporation from polyvinyl chloride filled with dispersed carbon fiber

The mechanism of dioctyl phthalate evaporation from polyvinyl chloride films filled with dispersed carbon fiber was studied by thermal gravimetric analysis. At a low degree of filling, the evaporation is controlled by the diffusion of the plasticizer in the polymer. At increased degrees of filling,...

Description
Summary:	The mechanism of dioctyl phthalate evaporation from polyvinyl chloride films filled with dispersed carbon fiber was studied by thermal gravimetric analysis. At a low degree of filling, the evaporation is controlled by the diffusion of the plasticizer in the polymer. At increased degrees of filling, evaporation of the plasticizer from the film surface becomes the limiting step. The change in the plasticizer evaporation mechanism is associated with the effect of the carbon fiber on the formation of the polymer matrix structure and on the plasticizer distribution.
