28428-42-4 - Introduction
2-Propenoic acid, 2-methyl-2-propenoate is a polymer, commonly known as Methyl Methacrylate (MMA), polymer with ethene and oxiranylmethyl.
Nature:
1. MMA is a colorless and transparent liquid with a pungent smell.
2. It has good optical properties, including high transparency and high refractive index.
3. It has low density and good electrical insulation performance.
4. It has good weather resistance and is not susceptible to ultraviolet radiation and chemical corrosion.
Use:
1. MMA is the main raw material of polymethyl methacrylate, polymethyl methacrylate is widely used in the manufacture of transparent plastic products, such as plastic glass, optical fiber, TV screen, etc.
2. It can also be used in the manufacture of surface coatings, adhesives, packaging materials and medical devices.
3. MMA is also used as an ingredient in cosmetics, dental fillers and medical osteosynthesis materials.
Preparation Method:
The main preparation method of MMA is through the esterification reaction of methanol and methyl acrylate. The reaction requires the presence of a catalyst and is carried out at an appropriate temperature and pressure.
Safety Information:
1. MMA is a volatile liquid, exposure to or inhalation of high concentrations of MMA vapor may cause irritation to the eyes, skin and respiratory system.
2. When handling MMA, wear protective glasses, gloves and protective clothing.
3. avoid exposure of MMA to fire sources to prevent explosion.
4. in the process of using MMA, to maintain good ventilation conditions.
5. Waste disposal should comply with local regulations and MMA should not be dumped into the environment.
Please note that MMA is a chemical. Please read the relevant safety data sheet and follow the correct operating methods before use. Safety practices should be followed when handling chemicals.
