Studies on the Thermomechanical Behaviours of PS: Pmma Blend

Abstract

Polymer blending has become a technique for providing materials with extended useful properties beyond the range that can be obtained from single polymer equivalent. The tensile strength, elongation and thermal degradation profiles of PS: PMMA blends were investigated using Tensiometric and TGA methods. The highest tensile strength and elongation were prominent at 0.164 and 0.371 PMMA base mole fractions. The optimal temperature of blend degradation stabilizes are at 0.164, 0.228 and 0.019 PMMA base mole ratios. Thus, it is advisable to blend at these compositions.
