High Purity Glycidyl methacrylate CAS 106-91-2 GMA

Description

Because there are two functional groups in GMA molecule, active vinyl group and epoxy group with ionic reaction, which can be polymerized by functional group or ionic reaction, GMA can be used to modify vinyl polymer and polycondensation polymer. GMA can intervene in polymerization in three ways. One is to make epoxy group on branch chain during ethylene polymerization, namely "O" polymer [2]; The second is epoxy ring opening, which makes vinyl on the branch chain, namely "V" polymer [3]; The third is that the compounds with active hydrogen react with GMA to form a chain on the epoxy group. Using any of the above three methods, the polymer is modified during polymerization. In terms of coatings, the addition of GMA can improve the hardness, glossiness, adhesion and weather resistance of the film, and can be used for acrylic coatings, acrylate coatings, alkyd resin coatings, vinyl chloride resins and some water-based coatings. It is used for adhesives and non-woven fabrics. When it is used for acrylic emulsion, it can improve its adhesion to metal, glass, cement, polyfluoroethylene, etc; When the non-woven fabric is used for synthesizing latex, its washing resistance is improved without affecting the hand feeling. When it is used in the processing of synthetic resin materials, it can improve the spray formability, extrusion formability, and obviously improve the adhesion between resin and metal. It is used for synthetic fibers. For fibers with poor dyeing, it can improve their dyeing strength, color fastness, wrinkle and shrink resistance. This product can improve the sensitivity, resolution and corrosion resistance of photosensitive resin. Grafting with polyolefin can improve tensile strength and bending strength. In addition, the product can also be used as the raw material of ion exchange resin, chelating resin, medical selective filtration membrane, anti coagulant, dental material, and insoluble adsorbent. It is also used for rubber modification.
