General Description

2-Propenoic acid, 2-methyl-, 2-[4-(2-hydroxy-2-methyl-1-oxopropyl)phenoxy]ethyl ester is a chemical compound that is commonly known as methyl methacrylate. It is an ester of methacrylic acid and is widely used in the production of various plastics, adhesives, and coatings. It is a colorless liquid with a sweet odor and is highly flammable. Methyl methacrylate is a key ingredient in the manufacture of acrylic resins and polymers, which are then used in a wide range of products such as dental fillings, artificial nails, and automotive body panels. However, exposure to this chemical can cause irritation to the skin, eyes, and respiratory system, and it is considered a potential carcinogen.

Method for preparing polymerizable photoinitiators

The invention discloses a method for preparing polymerizable photoinitiators. The polymerizable photoinitiators are prepared from methacrylic acid and 2-hydroxyl-4'-(2'-hydroxyethoxy)-2-methyl propiophenone by the aid of direct esterification processes. The use quantity of polymerization inhibitors in a reaction system accounts for 0.01%-0.5% of the mass of the methacrylic acid, the use quantity of methane sulfonic acid which is a catalyst accounts for 0.1%-2% of the mass of the methacrylic acid, and a molar proportion of the methacrylic acid to the 2-hydroxyl-4'-(2'-hydroxyethoxy)-2-methyl propiophenone is 1:1-1.2. Each polymerization inhibitor is methoxyphenol or hydroquinone or 2-tertiary butylhydroquinone, and a solvent is toluene or dimethylformamide or tetrahydrofuran. The method has the advantages that the polymerizable photoinitiators are excellent in compatibility with monomers and resin in photo-curing systems fragments obtained after the polymerizable photoinitiators are subjected to illumination pyrolysis are low in migration rate in cured films and are anti-yellowing, excellent initiation effects can be realized, and the method can be applied to the field of photo-cured coating, printing ink, adhesive and the like; the method for synthesizing the polymerizable photoinitiators is low in cost, processes for preparing the polymerizable photoinitiators are simple and convenient, and obvious application effects can be realized.
