摘要: Abstract The cloud point temperatures of four series epoxy/polystyrene blends have been experimentally determined as a function polymer mass and system composition. phase diagrams show an UCST behaviour, increasing incompatibility the molar increases. Flory–Huggins theory with concentration-dependent interaction parameter has developed to study compatibility two polymers in presence spherical nanoparticles. This first compared experimental curve absence nanoparticles, secondly it used predict thermodynamic behaviour different volume fraction Nanoparticles coated types functional groups tested. It can be concluded that inclusion nanoparticles increases compatibility. Moreover parameters obtained these systems for time.
