Description

2-Propenoic Acid, 2-Chloro-, 2-Methylpropyl Ester is a specialized acrylate ester monomer, distinguished by the presence of a reactive chlorine atom on the α-carbon of the acrylic acid backbone. This compound is valued for its dual functionality, offering both the polymerizable acrylate group and a site for further chemical modification, making it a versatile building block for advanced materials. It is primarily sought by R&D chemists and formulators in the polymer and specialty chemical industries for creating custom resins, adhesives, and functional coatings with tailored properties.

Application

• Synthesis of specialty polymers and copolymers for enhanced adhesion, chemical resistance, or weatherability.
• Production of reactive diluents and cross-linking agents in UV-curable inks, coatings, and adhesives.
• Manufacture of pressure-sensitive adhesives (PSAs) and sealants with modified tack and peel strength.
• Intermediate for pharmaceutical and agrochemical actives, leveraging the reactive chloro and ester groups.
• Modifier for acrylic and methacrylic resin systems to introduce chlorine for flame retardancy or other functional traits.
• Research and development of novel polymeric materials in academic and industrial laboratories.
