Luperox® for Acrylic Polymers & Coatings Resins

Luperox® for acrylics includes a variety of solutions for solvent-borne or water-borne coating resins synthesis

Peroxide Benefits

As compared with traditional options like azo-initiators or persulfates, organic peroxides offer a range of benefits:

  • No sulfuric acid by-products generated
  • Increased monomer conversion, low residuals
  • Lower molecular weight, lower solution viscosity
  • Narrow molecular weight distribution
  • Higher solids content resin solutions, leading to reduction in volatile organic contents


Arkema filed the original patent on use of tertiary-amyl organic peroxides for coatings resins synthesis.  As compared with tertiary-butyl organic peroxides, t-amyl products are well suited to coatings resins synthesis for these reasons:

  • More polymer chains generated, with lower molecular weight
  • Radicals generated are more selective, reducing hydrogen abstraction (crosslinking)
  • Less long chain branching, better control over molecular weight and viscosity

Tert-amyl vs. tert-butyl peroxides for coatings resins

The lower energy ethyl radical generated by the decomposition of a tert-amyl organic peroxide is more selective than the methyl radical generated by a tert-butyl analog product. Selectivity leads to less branching (hydrogen abstraction) and results in resins with lower viscosity and lower molecular weight.
