Molar Mass 398.5 g/mol
Properties Powder, technically pure
Description
White, free-flowing powder, consisting of technically pure Bis(4-tert. butylcyclohexyl) peroxydicarbonate. This cyclo-aliphatic peroxydicarbonate is used as an Initiator (radical source) in the polymerisation of monomers, e.g. vinyl chloride and acrylates, and as a substitute for AIBN.

Application
VINYLCHLORIDE:
Polymerisation of vinyl chloride in mass or suspension. Temperature range: 45-60°C. Dosage: 0.02-0.1% as supplied. We recommend a combination with thermally more stable peroxides, e.g. Dilauroyl peroxide (LP). A well-balanced combination produces an almost constant rate of polymerisation throughout the reaction period.
OTHER MONOMERS:
Initiator for the polymerisation in bulk of acrylates. Temperature range: 40-70°C. Dosage level: 0.02-0.15% as supplied. In combination with thermally more stable peroxides, low residual monomer contents can be achieved.
RADICAL SYNTHESIS: Initiator for radical reactions at mild temperatures. Substitute material for azobis (isobutyronitril) (AIBN). We recommend a combination with thermally more stable peroxides, e.g. Dilauroyl peroxide (LP).
Further information on suitable initiators for the polymerisation of monomers is given in our application brochures on this subject.
