tert-butyl monoperoxymaleate

Tert-butyl monoperoxymaleate (CAS 1931-62-0) is an organic peroxide acting as a radical source in polymer manufacturing and curing systems.

Where is tert-butyl monoperoxymaleate used?

• Plastics and polymer production: initiates free-radical polymerization of vinyl and acrylic monomers for resins and thermoplastic compounds
• Coatings: curing agent in unsaturated polyester and acrylic systems where crosslink density affects film performance
• Adhesives and sealants: supports room- or elevated-temperature cure schedules for structural bonding
• Elastomers: cross-linking initiator for defined network density in rubber compounds and sealant matrices
• It delivers controlled radical generation at moderate temperatures for initiating polymerization.

Good to know: Often phlegmatized in a plasticizer or solvent to meet transport and handling requirements. Technical-grade material is standard, with active oxygen content as the primary specification parameter.

Commercial specifications

• Active oxygen content as primary specification parameter
• Concentration levels vary by supplier to comply with regulatory classification thresholds
