During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...

The positron annihilation lifetime spectroscopy was used to investigate the free volume hole size of ethylene octane copolymers as a function of deformation in the range from 0 to 110% in steps of 10%. For each degree of deformation a series of 5–6 positron annihilation lifetime spectra was collected in situ. All spectra of a given series were analysed simultaneously. They were resolved into th...

Although the technical and economic properties of standard polymer photovoltaic (PV) materials (ethylene-vinyl acetate (EVA) encapsulant fluorine-containing polyethylene terephthalate (PET) backsheet) meet basic requirements, more sustainable polyolefin-based encapsulants backsheets have been developed. These new polyolefin to prove their performance compared established in terms electrical mod...

Since 1940, mass production of polyolefin plastics produced annually has increased rapidly [1]. The most common plastics, which account for approximately 80% the European plastic demand, are: Polyethylene (PE), Polypropylene (PP), Poly (Vinyl Chloride) (PVC) and Polystyrene (PS) (Figure 1) [2]. Therefore, materials have experienced a substantial expansion, are used nowadays. These wide range ap...
