The Improvement of Polyvinyl Chloride Synthesis Using Different Approaches
Abstract: Polyvinyl chloride (PVC) is produced by the polymerization of the vinyl chloride monomer either by direct chlorination of olefins or by addition of hydrogen chloride to acetylene. The polymerization conditions are: heat, peroxides or oxidizing agents with basic structure as -CH2CHCl.CHCl-CH2.CHCl-. Polyvinyl chloride is a thermoplastic and its plasticity can be increased by incorporating ‘plasticizers’ of relatively low molecular weight organic materials during molding or extrusion. PVC has high hardness …

NBR/PVC Blends Production, Testing and Applications: An Overview
Abstract: PVC due to its polar nature allows preparation of compatible blends with other polymers. Main and unique property of NBR is its oil resistance and it is used in such application even after higher cost than natural and synthetic rubbers. PVC possesses good oil resistance but needs additional plasticizer which can be extracted by solvents; thus, plastic becomes hard and brittle during the life cycle of the product. There are …

Environmental implications of stubble and their usages as soil and concrete reinforcement
Abstract: Stubble burning has been reckoned among the major contributors to air pollution, especially in North India. It is a significant source of gaseous pollutants causing serious damage to human health and the environment. The situation is more hazardous due to the intensive rice-wheat rotation system which generates a large amount of stubble with no significant use as good as burning due to poor knowledge of the management of stubble. It …
