4-Hydroxybutyl acrylate
4-Hydroxybutyl acrylate (CAS 2478-10-6), with the linear formula H₂C=CHCO₂(CH₂)₄OH and a molecular weight of 144.17 g/mol, is a versatile functional monomer. It possesses both acrylate and hydroxyl groups, enabling its use in various polymerisation processes and chemical synthesis. This compound is valuable in materials science for creating polymers with specific properties and as a building block in organic synthesis.
Polymer Synthesis
Utilised as a monomer in the production of acrylic polymers and copolymers. The hydroxyl group allows for further crosslinking or modification, enhancing polymer properties such as adhesion and flexibility.
Coatings and Adhesives
Incorporated into formulations for coatings and adhesives, contributing to improved substrate wetting and bonding characteristics. Its structure offers good weatherability and chemical resistance in cured materials.
Organic Synthesis Intermediate
Serves as a reactive intermediate in the synthesis of more complex organic molecules. The acrylate functionality allows for Michael additions and polymerisation, while the hydroxyl group can undergo esterification or etherification.
Materials Science Research
Employed in research and development for novel material design, including functional polymers, hydrogels, and surface modification agents.
