Polyvinyl chloride (PVC) is one of the polymers which play a large role in sustainable development. However, the problems of poor impact strength, difficult processibility, and poor thermal stability are some of the inherent features which are associated with the most widely used polymer PVC. To overcome these limitations, polymeric or non-polymeric modifiers may be used which are often referred to as impact modifiers or processing aids. However, by the usage of a non-polymeric modifier, one of the properties of the polymer is enhanced but it induces deterioration in the other properties of the same. So, by incorporating polyethyl acrylate (PEA) as the polymeric modifier in PVC, it has been observed that the mechanical properties of the latter are largely modified by increased elongation at break and toughness. However, the mechanical parameters of modulus and ultimate tensile strength are not improved by the influence of PEA. With this basic observation, the present study aims at improving the properties of PVC even further in terms of modulus and ultimate tensile strength by incorporating nano calcium carbonate (nano CaCO3) within it and estimate the dynamics of the incorporated system over a range of added nanofiller.
