“…Examples for polyvinyl alcohols that are semiconductors are those doped with CoCl 2 , NiCl 2 , and other transitional metal halides 4–6. Research work on the electrical and optical properties of polyvinyl acetate is rare 7. However, as it is well known, polyvinylacetate can be easily hydrolized to polyvinylalcohol.…”

Polyglycerol (PG) and polytriethanolamine-(PTEA) have been prepared. The electrical resistivity () and the optical absorption of polyvinylacetate (PVAc) doped with polyglycerol (PG), polyaniline (PA), and polytriethanolamine (PTEA) have been studied. It was found that the conduction was mainly ionic in the temperature range from 20 to 120°C. The resistivity decreased with the increase of the dopant cocentration. The optical absorption spectra were determined in the wavelength range 400 -2500 nm. The analysis of the absorption spectra showed that the intensity of the bands is remarkably affected by the dopant concentration. The optical energy gap of pure PVAc and the samples containing different dopants were estimated.

Cigarette butts are one of the toxic residues and have a very serious impact on the environment. Recycling cigarette butts has a great advantage in saving the natural source and solving environmental problems. Cellulose diacetate obtained from extraction, purification and acid hydrolysis of cigarette butts and then was blended with low molecular weight partially hydrolyzed polyvinyl alcohol. The blend of cellulose diacetate and partially hydrolyzed polyvinyl alcohol was characterized by Fourier transform infrared spectroscopy and differential scanning calorimetry. To evaluate the viscoelastic properties of the blends dynamic mechanical analysis was performed. The lap shear strength and the 180° peel strength of the adhesive were estimated according to the content of the blends and the biodegradability in water was confirmed. The experimental results showed that the use of cellulose diacetate obtained from cigarette butts in the composition of biodegradable hot melt adhesives can be of great help in solving environmental problems caused by petroleum-based polymers and waste.
