In March 2026, the differences and connections between POE-grafted maleic anhydride (POE-g-MAH) and maleic anhydride (MAH), core materials in the chemical industry, have attracted industry attention. Though closely related, they belong to different categories: MAH is a basic small-molecule chemical raw material, while POE-g-MAH is a modified polymer material derived from it. They differ significantly in structure, performance and application, are irreplaceable for each other, and jointly serve as important supports for plastic modification, resin synthesis and other fields. MAH is a highly polar small molecule with high reactivity, prone to sublimation and hydrolysis. Its core application is organic synthesis, serving as the main raw material for the production of unsaturated polyester resins. POE-g-MAH forms a semi-polar elastomer by grafting polar groups of MAH onto a POE matrix, boasting excellent thermal stability. As a plastic modification additive, it has both compatibilizing and toughening functions, which can improve the performance of nylon, polyolefin and other materials, and solve the compatibility problem between polar and non-polar materials. MAH is also a key raw material for preparing POE-g-MAH, realizing the transformation from basic raw material to modified product through grafting reaction and forming a closely linked industrial chain upstream and downstream.
