Route of Synthesis (ROS) of 3-Ethyl-3-(methacryloyloxy)methyloxetane CAS 37674-57-0
ConditionsYieldWith 2,2'-azobis-(2,4-dimethylvaleronitrile) In 3-methoxy butanol; 3-methoxybutyl acetate at 90℃; for 8h;Experimental Procedure Example 15; The inside of a 1-liter flask equipped with a reflux condenser, dropping funnels, and a stirrer was allowed to be a nitrogen atmosphere by feeding a suitable amount of nitrogen thereto; 150 parts by weight of 3-methoxy-1-butanol and 110 parts by weight of 3-methoxybutyl acetate were placed in the flask and heated to 90°C with stirring. Next, a solution was prepared by dissolving 60 parts by weight of methacrylic acid (MAA), 160 parts by weight of a 50:50 (by mole) mixture (E-DCPA) of 3,4-epoxytricyclodec-9-yl acrylate (belonging to compounds represented by Formula (1a-1)) and 3,4-epoxytricyclodec-8-yl acrylate (belonging to compounds represented by Formula (1a-2)), and 80 parts by weight of (3-ethyl-3-oxetanyl)methyl methacrylate (OXMA) in 170 parts by weight of 3-methoxybutyl acetate. The solution was added dropwise into the flask using a dropping pump over about three hours. Separately, 50 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile) as a polymerization initiator was dissolved in 220 parts by weight of 3-methoxybutyl acetate to yield a solution, and this solution was added dropwise into the flask using another dropping pump over about five hours. After the completion of dropwise addition of the polymerization initiator, the mixture was held at the same temperature for about three hours, then cooled to room temperature, and thereby yielded a copolymer solution having a viscosity at 23°C of 98 mPa.s, a solid content of 31.5 percent by weight, and an acid value as a solution of 36.3 mg-KOH/g. The formed copolymer had a weight-average molecular weight (Mw) of 8700 and a molecular weight distribution of 2.06.

Use Pattern3-Ethyl-3-(methacryloyloxy)methyloxetane CAS #: 37674-57-0 is a commonly used photoinitiator that can undergo copolymerization with other monomers such as methyl methacrylate and acrylic esters to form high molecular weight polymers. These polymers exhibit excellent optical properties and abrasion resistance, making them widely used in coatings, adhesives, and optical materials.UV-curable coatings prepared from 3-Ethyl-3-(methacryloyloxy)methyloxetane can rapidly cure under ultraviolet (UV) irradiation. These coatings offer good adhesion, abrasion resistance, and chemical resistance, making them suitable for coating surfaces such as wood, plastics, and metals.
