Applications
Luperox 554M75 polymer initiator is a tert-amyl peroxyester used for the polymerization of vinyl chloride or acrylic monomers. Using Luperox 554M75 will help reduce the formation of "fish eye" defects in PVC resins because the polymerization kinetics are better controlled. For acrylic polymerization, the recommended process temperature is 50°C to 80°C. Tert-amyl peroxyesters are very efficient, producing lower-energy radicals that can narrow the polydispersity of acrylic resins and produce a lower overall solution viscosity.
