This article will introduce the use of methyl acrylate, welcome to learn together!
Because there are two functional groups in the GMA molecule, the active vinyl group and the ionic reaction epoxy group, they can be polymerized in a functional group way and also in an ionic reaction way, so they can be used for the modification of ethylene-type polymers and polycondensation polymers, GMA can intervene in polymerization in three ways, one is ethylene polymerization so that the epoxy group is located on the branched chain, that is, "O GMA can intervene in the polymerization in three ways: firstly, when ethylene is polymerized so that the epoxy group is on the branched chain, i.e. "O" type polymer [2]; secondly, when the epoxy opens the ring so that the vinyl group is on the branched chain, i.e. "V" type polymer [3]; thirdly, when a compound with active hydrogen reacts with GMA and opens the ring on the epoxy group to form a chain. Using any of the above three ways, the polymer is modified in the polymerization reaction in time. In coatings, because of the presence of GMA, the hardness, gloss, adhesion and weather resistance of the coating film can be improved, and can be used in acrylic coatings, acrylate coatings, alkyd coatings, vinyl chloride resins, and certain water-based coatings.
When GMA is used for acrylic emulsions, binders, and nonwoven fabrics, it improves adhesion to metals, glass, cement, and polyfluoroethylene; when it is used for nonwoven fabrics of synthetic latexes, it improves their washability without affecting their handfeel. When treated with synthetic resin materials, this improves injection moldability, extrusion moldability, and to significantly improve adhesion to resins and metals. When used for synthetic fibers, this can improve the coloring power of poorly dyed fibers, and improve the color fastness of Zhuo, and improve anti-wrinkle and anti-shrink ability. This product can improve the sensitivity, resolution and corrosion resistance of photosensitive resin. This product can improve tensile strength and flexural strength by grafting with polyolefin. In addition, this product can be used as raw material for ion exchange resin, hybrid resin, medical selective filtration membrane, anti-coagulant, dental material, non-soluble adsorbent, etc. It is also used for rubber modification.
