✦ Synopsis
compatibility study was conducted on the system poly(vinylidene fluoride)/polystyrene in the presence of carbon black, metallic copper, YBaCuO ceramics and poly(viny1 acetate). From T, measurements the volume fractions of the respective minority polymer in either phase were calculated, and applying an expression proposed by Kim and Burns, the Flory-Huggins polymer-polymer interaction parameters xlZ were determined. The results show that a greater portion of polystyrene is dissolved in the poly(vinylidene fluoride)-rich phase than vice versa, the dissolution level being a function of the nature of the third component added to the blend.
