For the synthesis of medical polymer materials, thermosetting coatings and adhesives, etc.

Basic Information

Physical and chemical properties

Colorless, transparent and easy-flowing liquid. Dissolve in a common organic solvent. Mixed with water.

Application

1, mainly used for the modification of resin and paint. Colymerization with other acrylic acid monomers, can make the side chain acrylic resin containing active hydroxyl group, can be esterified and cross-linking reaction, synthesize insoluble resin and improve adhesion, can be used as a fiber treatment agent. Combine the reactions with melamine-formaldehyde (or urea-formaldehyde) resin and epoxy resin to make two-component coatings. Join the premium car paint, can maintain the mirror luster for a long time. It can also be used as adhesive and medical polymer.

2, for the production of coatings, automotive topcoat and primer resin, but also can be applied to photopolymer resin, printing plate, ink, gel (contact lenses) and listening materials coating, transmission electron microscope (TEM) and optical microscope (LM) embedded reagents, especially for "sensitive antigen site" hydration samples. White water, sticky, thinner than water, more permeable than any resin and monomer. Especially for working on bone, cartilage and impermeable plant tissues.

3, the plastic industry is used in the manufacture of the acrylic acid dendrite containing the active hydroxyl group. Coating industry and epoxy resin, diisocyanate, melamine formaldehyde resin configuration for making two-component coatings. The oil industry is used as an additive in lubricating oil washing. Used in the electronics industry as a dehydrating agent for electron microscopy. Adhesive used in the textile industry to make fabrics. Used as a chemical reagent in the analytical chemistry. In addition, it is also used in water-mixed-soluble embedded agent, used for the synthesis of medical polymer materials, thermosetting coatings and adhesives.

Methods of production

Add iron thiocyanate, tetramethylamlammonium chloride and a little hydroquinone to methacrylic acid, stir and heat to 90℃. Under nitrogen protection, ethylene oxide gas is reacted for about 2h. The reaction product is cold to 60℃, add a small amount of hydroquinone after reduced pressure distillation, collect 86-89℃(0.67kPa) fraction is the finished product, the yield of more than 80%.2. Potassium methacrylate salt and chlorine ethanol react in the presence of polymer resist to form crude methacrylate-2-hydroxyethyl ester, which is refined by salting out analysis and refining.
