Butyl methacrylate, methyl methacrylate, 1-vinyl-2-pyrrolidone polymer - Introduction
1. Butyl methacrylate (butyl methacrylate):
Properties: Colorless liquid with small vapor pressure and low flash point. It is insoluble with some organic solvents and water, but soluble in alcohols and ethers. It can form a polymer by free radical polymerization.
Uses: Widely used in polymers, coatings, adhesives and inks. For example, it can be used as a base material for adhesives, as a monomer for modifying resins, and as a coating component in abrasion resistant coatings.
Preparation method: Generally, it is synthesized by transesterification reaction of butanol and methacrylic acid.
Safety Information: Butyl methacrylate is irritating and may cause eye and skin irritation. Therefore, in use should pay attention to protection, and ensure good ventilation.
2. Methyl methacrylate (methyl methacrylate):
nature: colorless liquid, with a special pungent odor. It has a low vapor pressure and can be dissolved in water and many organic solvents. It is also a monomer for free radical polymerization.
Application: widely used in plastic products, coatings, textiles, adhesives and dental materials and other fields. It can be used to prepare polymethyl methacrylate (PMMA), which has excellent transparency and weather resistance.
preparation method: generally, myricetin methyl ester is prepared by the reaction of benzaldehyde and hydrocyanic acid, and then it is transesterified with methanol to obtain methyl methacrylate.
Safety Information: Methyl methacrylate is irritating and sensitizing and may cause irritation to the eyes, skin and respiratory system. In the use of the process should pay attention to protection, and ensure adequate ventilation.
3. 1-vinyl-2-pyrrolidone polymer (1-vinyl-2-pyrrolidone polymer):
Properties: White or light yellow solid, odorless. It can be dissolved in water and some organic solvents and has good solvent properties. It is a high molecular polymer.
Uses: Because of its excellent solvent characteristics, the polymer is commonly used as a film former, viscosity enhancer, emulsifier and cosolvent. In addition, it is also widely used in drug controlled release systems, dyes and coatings.
Production Method: Generally, 1-vinyl-2-pyrrolidone is reacted with an initiator to carry out radical polymerization synthesis.
SAFETY INFORMATION: 1-Vinyl-2-pyrrolidone polymer is considered to be low toxic under normal conditions, but inhalation of high concentrations may cause respiratory irritation. In use should pay attention to protection, and ensure adequate ventilation.
