Product Name:Octadecyl polyoxyethylene methacrylate
English Name:Octadecyl polyoxyethylene methacrylate
CAS No.:70879-51-5
Aliases:OEMA, Octadecyl ethoxylate methacrylate, Stearyl polyoxyethylene methacrylate
Molecular Formula:CH2=C(CH3)COO(CH2CH2O)nC18H37
Physical Properties:White to light yellow waxy solid or viscous liquid; melting point approximately 30-50°C; density about 0.92 g/cm³; flash point ≥110°C. Insoluble in water, soluble in ethanol, acetone, toluene and other organic solvents; exhibits good surface activity and polymerization reactivity.
Uses:Mainly used as a monomer for synthesizing alkali-soluble associative thickeners, providing excellent thickening efficiency and serving as a substitute for hydroxyethyl cellulose and Rhodia SIPOMER BEM. Widely applied in architectural coatings, paper, adhesives and textile industries. Also used as a macromonomer for polycarboxylate superplasticizers and dispersants, as well as in the production of oilfield drag reducers and friction-reducing slick water.
Technical Specifications:
Purity: ≥60%
Appearance: white to light yellow waxy solid or viscous liquid
Acid value: ≤5 mg KOH/g
Density: approx. 0.92 g/cm³ (25°C)
Flash point: ≥110°C
