Products Description of Poly(acrylic acid)CAS#9003-1-4

Acrylic resin (MethylMethacrylateResin), commonly known as organic glass, is a polymer compound made from methyl methacrylate. Commonly used synthesis methods include anionic polymerization, solution polymerization, bulk polymerization, and suspension polymerization. In addition, the resin has excellent properties such as easy coloring, light weight, not easy to break, and good processing performance. Therefore, it is often used as a substitute for glass, optical lenses, lenses, etc. In addition, with the development of acrylic resin and its modified polymers, acrylic resin is also widely used in the fields of pharmaceutical preparations and coatings.

Product Application of Poly(acrylic acid)CAS#9003-1-4

1. Pharmaceutical preparations: acrylic resin is a widely used polymer material in pharmaceutical preparations because of its safety, stability, inertness and non-irritation. Acrylic resin can be divided into two categories: methacrylic acid copolymer and methacrylate copolymer. Due to the different copolymer components and proportions, it has multiple characteristics of being soluble in gastric juice and intestinal juice or insoluble in water. Therefore, it is often used for film coating, solid dispersion, sustained-release micropills, sustained-release skeleton tablets and other pharmaceutical uses. In addition, acrylic resin has better performance as a pharmaceutical excipient and has broad development space.

2. Coatings: Acrylic resin has light color, good transparency, excellent light and color retention; it does not decompose or change color at high temperature, has good resistance to acid, alkali, salt, grease, detergent and other chemicals, and has excellent construction performance. In particular, it can be widely modified with various chemical monomers and new materials, endowed with various special properties, and prepared new varieties of acrylic resin coatings.
