Abstract
The preparation and characterization of composite polymer
of poly (vinyl chloride) (PVC) doped with different concentration of poly
(methyl methacrylate) (PMMA) have been investigated. These composite
films were prepared by casting technique, the organic compound
Tetrahydrofuran (THF) was used as a solvent for poly (vinyl chloride) (PVC)
and poly (methyl methacrylate) (PMMA), the solution was stirred for 12 hours
and put in petri dishes for 12 hours to evaporate the solvent, the final product
was a homogenous films.
These composite films were characterized by X-ray diffraction (XRD)
and suggest generally an amorphous nature to all samples. Fourier transform
infrared spectroscopy (FTIR) spectra indicate complex formation between the
components (PVC-PMMA). The mechanical properties of the films have been
investigated by the UNIVERSALMATERIALS TESTING MACHINE to
study the change of mechanical properties of poly (vinyl chloride) (PVC) by
adding poly (methyl methacrylate) (PMMA). The thermal stability for these
films was investigated by thermo-gravimetric analyzer to study the effect of
doping PVC with PMMA on the thermal stability of poly (vinyl chloride)
(PVC).
