Description

Diallyl Succinate is a high-purity, unsaturated diester monomer with the CAS registry number 925-16-6. This compound serves as a versatile chemical intermediate and cross-linking agent, valued for its ability to introduce reactive allyl groups into polymer backbones. It is essential for manufacturers in the polymer, specialty chemical, and advanced materials sectors seeking to develop products with enhanced thermal stability, mechanical properties, and tailored reactivity.

Application

• Polymer Synthesis & Modification: A key monomer for producing specialty polyesters, polyamides, and alkyd resins, imparting cross-linking sites for improved film hardness and chemical resistance.
• Thermoset Resins: Used as a reactive diluent and cross-linker in unsaturated polyester resins (UPR) and vinyl ester resins for composites, coatings, and laminates.
• Adhesive & Sealant Formulations: Incorporated to enhance the cure speed, adhesion, and flexibility of industrial adhesives and sealants.
• Specialty Plasticizers: Acts as an internal plasticizer or co-monomer to modify the flexibility and processability of rigid polymers.
• Organic Synthesis Intermediate: Serves as a building block in the synthesis of more complex molecules for pharmaceuticals, agrochemicals, and fine chemicals via its reactive double bonds.
• Coatings & Inks: Utilized in radiation-curable (UV/EB) coatings and printing inks to promote rapid curing and durable film formation.
