Comparative studies of the rheological behaviour of oil epoxy and oil polyesteramide blends with polymethacrylic acid

Polymer blends have replaced a variety of pristine polymers in different sectors due to their desired synergetic properties such as durability, heat resistance, reduced wear & tear, flexibility, chemical resistance and longer shelf life that can be achieved by making minor alterations in their compositions. The modification of polymer blends by using sustainable resource based polymers can not only fulfil our ecological but also our economic and social needs. The present work reports the compatibility studies of oil derived epoxy and polyesteramide blends with polymethacrylic acid (PMA). The aim is to highlight the role of rheology in predicting the compatibility of these blends in the solution and solid phases which is a crucial parameter that decides the processibility and viability of these materials for commercialization.
