Main use of glycidyl methacrylate
Since the GMA molecule has two functional groups, an active vinyl group and an ionic reactive epoxy group, it can be polymerized in a functional group or polymerized by an ion reaction method, so it can be used for an ethylene type polymer and a polycondensation type polymer. Modification, GMA can intervene in three ways. One is that when ethylene is polymerized, the epoxy group is located on the branch, ie, the "O" type polymer ; the second is the epoxy ring opening, making the vinyl Located on the branch, that is, the "V" type polymer ; the third is that the compound having active hydrogen reacts with GMA and is opened to form a chain on the epoxy group. The polymer is modified upon polymerization by any of the above three methods. In terms of coatings, the addition of GMA can improve the hardness, gloss, adhesion and weather resistance of coatings. It can be used in acrylic coatings, acrylate coatings, alkyd coatings, vinyl chloride resins and some waterborne coatings.
Used in adhesives and non-woven fabrics, when used in acrylic emulsions, it can improve the adhesion to metals, glass, cement, polyvinyl fluoride, etc.; when used to synthesize non-woven fabrics of latex, it does not affect the hand. In case, improve the washability. When used in the processing of synthetic resin materials, it can improve the spray formability, extrusion formability, and significantly improve the adhesion of the resin to the metal. Used in synthetic fibers, it can improve the coloring power and improve the coloring fastness and improve the anti-wrinkle and anti-shrinking ability. This product can improve the sensitivity, resolution and corrosion resistance of the photosensitive resin. This product is grafted with polyolefin to improve tensile strength and flexural strength. In addition, this product can also be used as a raw material for ion exchange resins, chelating resins, medical selective filtration membranes, anti-coagulants, dental materials, and solubilizing adsorbents. Also used for rubber modification.
