Spectroscopic Correlation of Mechanical Properties of PVC/PMMA Polymer Blend

Abstract

PVC/ PMMA polymer blends are characterized at molecular level by FTIR-ATR spectroscopy providing important insight into the
molecular interactions responsible for the enhancement of its mechanical properties. The changes in mechanical properties are reflected by the changes in the FTIR-ATR spectrum. The mechanical properties of such poly blends revealed a substantial increase in Young’s modulus and ultimate tensile strength after initial drop at 10% of PMMA. A comparative study of mechanical properties of PVC/ PMMA polymer blends with different weight percentage are carried out and their results are co-related with FTIR – ATR spectral studies and important conclusions are drawn about the possible molecular interactions between constituent polymers.
