9051-31-4 - Introduction
A poly(ethylene glycol) acrylate is a polymer that is prepared by reacting an acrylate with polyethylene glycol. Its properties are as follows:
1. Physical properties: poly(ethylene glycol) acrylate is a colorless to yellow liquid with low viscosity and high solubility.
2. Chemical properties: It is a cross-linkable polymer that can be cross-linked by ultraviolet light or chemical cross-linking agents. This gives it good durability and stability in many applications.
The main uses of poly(ethylene glycol) acrylate are as follows:
1. medical field: due to its good biocompatibility and degradability, poly(ethylene glycol) acrylate is widely used in the preparation of drug controlled release systems, biological materials and pharmaceutical carriers.
2. Adhesive: poly(ethylene glycol) acrylate can be used as an adhesive for the preparation of coatings, glues and adhesives.
3. Cosmetics: It is also used in the cosmetics industry and is used as an ingredient in emulsions, gels and resins.
There are two main methods for preparing
poly(ethylene glycol) acrylate: monomer polymerization and reaction. The monomer polymerization method is obtained by heating and reacting an acrylate monomer and polyethylene glycol under specific conditions. The reaction method is such that the prepared acrylate monomer and polyethylene glycol are added to a reaction vessel and reacted by heating and stirring.
Regarding safety information, poly(ethylene glycol) acrylate are generally considered to be relatively safe materials. However, during operation and use, care should be taken to comply with relevant safety operating procedures and avoid skin contact and inhalation. Wear appropriate personal protective equipment such as gloves and goggles when handling the substance. If necessary, refer to the specific safety data sheet and notes.
