Butyl methacrylate
Butyl methacrylate (CAS: 97-88-1), with the molecular formula CH2=C(CH3)COO(CH2)3CH3 and a molar mass of 142.20 g/mol, is a versatile acrylic monomer. It is a clear liquid primarily utilised in polymer synthesis for applications such as coatings, adhesives, and impact modifiers. Its reactive double bond allows for radical polymerisation, forming poly(butyl methacrylate) and copolymers with desirable material properties.
Polymer Synthesis
Butyl methacrylate is a key monomer for producing acrylic polymers and copolymers. These polymers find extensive use in the formulation of paints, coatings, and lacquers, contributing to durability and weather resistance.
Adhesives and Sealants
It serves as a comonomer in the production of specialised adhesives and sealants. The incorporation of butyl methacrylate can enhance flexibility, adhesion properties, and water resistance in the final product.
Impact Modification
Butyl methacrylate is employed as a comonomer to improve the impact strength and toughness of other plastics. Its inclusion in polymer blends can create materials with enhanced resistance to fracture and breakage.
Chemical Intermediates
As an organic building block, it is used in various chemical synthesis pathways. The ester and methacrylate functionalities offer reactive sites for further chemical transformations.
