Study on Grafting GMA on Polyolefin

Glycidyl methacrylate (GMA) is a reactive difunctional monomer containing carbon-carbon double bonds and epoxy groups in its molecule. It is a colorless and transparent liquid that is insoluble in water and easily soluble in organic solvents. The mucous membrane is irritating and almost non-toxic. GMA contains bifunctional groups, which can carry out free radical reactions as well as ionic reactions. Therefore, it has high reactivity and can be widely used in the synthesis and modification of polymer materials. Polyolefin (PE), polypropylene (PP), polyethylene-octene (POE) and other polyolefins can be modified by GMA grafting, which can significantly improve the adhesion and hydrophilicity of the polymer and its relationship with polar polymers Compatibility.

The polyolefin modified by GMA grafting can be used to modify plastics to obtain products with better performance. The epoxy groups contained in the GMA molecule can react with the end groups of some resins (such as carboxyl, hydroxyl, and amino), so GMA graft copolymers can be used as compatibilizers to modify plastics or be made with other plastics Total mixed gold.

GMA grafted polyolefinis a very practical modification method. Since graft modification has given polyolefins new characteristics, cheap petrochemical products such as polyolefins have a greater value-added. Therefore, in-depth research on graft modification, further improving the properties of polyolefins, and expanding its application fields are of great research significance.
