Butyl Acrylate Resin, identified by CAS number 9003-49-0, is a polymer derived from the monomer butyl acrylate. This resin is characterized by its excellent flexibility and low glass transition temperature (Tg), making it a sought-after material in industries requiring pliable and durable polymers. The monomer itself, butyl acrylate, is an ester formed from acrylic acid and n-butanol. Its chemical structure, featuring a butyl ester group attached to an acrylic backbone, dictates its polymerization behavior and the properties of the resulting resin.

The manufacturing of butyl acrylate monomer typically involves the esterification of acrylic acid with n-butanol in the presence of an acid catalyst. This process, often carried out with continuous water removal to drive the reaction forward, yields a clear, colorless liquid. Subsequently, this monomer can be polymerized to form butyl acrylate resin. The control over polymerization conditions is crucial for managing the molecular weight and the specific properties of the resulting resin, such as viscosity and film-forming capabilities.

The scientific appeal of butyl acrylate resin lies in its ability to enhance the mechanical properties of other polymers when used as a comonomer or additive. Its low Tg allows it to effectively plasticize polymer chains, reducing brittleness and increasing elongation at break. This makes it particularly useful in applications like adhesives, sealants, and coatings where flexibility under varying temperatures is a key performance indicator.

Furthermore, the chemical reactivity of the acrylate double bond allows butyl acrylate to undergo various addition and polymerization reactions, making it a versatile building block in polymer synthesis. Understanding the chemistry behind butyl acrylate resin is fundamental for developing new materials with tailored properties for advanced applications in construction, automotive, and consumer goods sectors.

For industries looking to procure high-quality butyl acrylate resin or its monomer, reliable sourcing is essential. Manufacturers and formulators often seek out suppliers who can provide detailed technical data, including specifications on purity, inhibitor content, and physical properties, to ensure optimal performance in their formulations. The consistent supply of butyl acrylate is a vital factor in maintaining product quality and production efficiency.
