| Application | widely used as comonomer in the preparation of organic glass, allyl methacrylate is an important cross-linking agent, which can provide effective bifunctional cross-linking in the second stage, and has good drug resistance, impact strength, adhesion, hardness, and low shrinkage. Used in dental materials, industrial paints, silicone intermediates, light stabilizers, optical polymers, elastomers and some ethylene, acrylic polymer systems. |
| production method | can be obtained by reacting acrylamide with allyl alcohol in concentrated acid and H 2 O 2, it can also be obtained by transesterification of Allyl acetate with methyl methacrylate. It can also be prepared by reacting methacrylic acid with allyl alcohol, using p-toluenesulfonic acid as a catalyst and refluxing in the presence of hydroquinone as a polymerization inhibitor. During the reaction, the generated water is continuously removed, and excess allyl alcohol is recovered by fractionation after the reaction is completed, the product was purified by distillation under reduced pressure. |
