CP 105 - Preparation Method

Open Data Verified Data

The glycidyl methacrylate monomer is a bifunctional monomer, which has both a double bond and an epoxy group, and can participate in a free radical and an ionic polymerization reaction, and can undergo a crosslinking reaction through an epoxy group. First, methacrylic acid was reacted with anhydrous Na2 C03 or NaOH to form sodium methacrylate Salt. Then, glycidyl methacrylate was prepared by reacting methacrylic acid with propylene oxide in a quaternary ammonium salt catalyst and a small amount of polymerization inhibitor.

introduction	glycidyl methacrylate (Glycidyl Methacrylate, abbreviated GMA) is a monomer with both acrylate double bonds and epoxy groups. The double bond of acrylate has high reactivity and can undergo self-polymerization reaction or copolymerization with many other monomers; while epoxy groups can react with hydroxyl, amino, carboxyl or acid anhydride to introduce More functional groups bring more functionality to the product. Therefore, GMA has a wide range of applications in organic synthesis, polymer synthesis, polymer modification, composite materials, UV curable materials, coatings, adhesives, leather, chemical fiber papermaking, printing and dyeing, etc.
application field	GMA is widely used in organic synthesis, polymer synthesis, polymer modification, composite materials, UV curable materials, coatings, adhesives, leather, chemical fiber papermaking, printing and dyeing, etc. GMA is used in powder coating: one of the main uses of GMA is to make powder coating matting resin for outdoor use. Due to its epoxy group, it has excellent powder coating leveling performance, weather resistance, salt spray resistance, high temperature resistance, and yellowing resistance. application of GMA in plastic modification: GMA can be grafted to polymer due to the existence of an acrylate double bond with high activity. GMA grafted POE is mainly used as polyester compatibilizer on the market. These functionalized polymers can be used as toughening agents to toughen engineering plastics or as compatibilizers to improve the compatibility of blend systems. Application of GMA in UV glue: Double bond is used for UV free radical monomer, free radical cation curing, because there are epoxy groups, so the curing speed is slow, but the bonding effect is better. GMA application in PCB ink: GMA can be used to produce PCB ink and green oil of acrylic system. Green oil is the circuit board ink.
Synthesis method	The two-step method is to first carry out a ring-opening esterification reaction between methacrylic acid and epichlorohydrin under the action of a ring-opening catalyst to generate 2-hydroxy3-chloropropyl methacrylate. Then 2-hydroxy3-chloropropyl methacrylate is subjected to a closed-loop reaction of dehydrochlorination in the presence of sodium hydroxide solid or aqueous solution, or reflux in acetone solution of potassium carbonate to obtain the product.
use	mainly used in powder coatings, but also used in thermosetting coatings, fiber treatment agents, adhesives, antistatic agents, vinyl chloride stabilizers, rubber and resin modifiers, ion exchange resins and adhesives for printing inks. Mainly used in acrylic powder coatings, latex coatings, textile leather finishing agents, adhesives, medicine, etc. GMA for short. Because its molecule contains carbon-carbon double bonds and epoxy groups, it can perform both free radical reactions and ionic reactions. Therefore, it has high reactivity and can carry out different reactions. It is an important fine chemical raw material. Commonly used in acrylic and polyester decorative powder coatings, industrial and protective topcoats, alkyd resins, adhesives, acrylic resin/emulsion synthesis, polyvinyl chloride coatings, substitutes for hydrogenated LER, plastic modifications, flame retardant materials, absorbent materials, polymer capsules, cross-linked monomers and reactive diluents
Production method	It is obtained by the reaction of sodium methacrylate and epichlorohydrin. Raw material consumption quota: 780kg/t methacrylic acid, 690kg/t epichlorohydrin and 330kg/t sodium hydroxide.
