Performance and mechanism analysis of EMA-GMA modified PMMA/ASA alloy

Abstract This article examines the impact of the EMA-GMA combination on the mechanical characteristics, fluidity, and glass transition temperature of PMMA/ASA alloy and uses scanning electron microscopy to characterize the modified PMMA/ASA alloy. The findings indicate that the addition of 5% EMA-GMA to PMMA/ASA significantly enhances its fracture resistance without compromising its stiffness. When the additional amount of EMA-GMA exceeds 10%, the mechanical properties and fluidity of the alloy begin to decline significantly. EMA-GMA within 15% can promote PMMA/ASA compatibility.
