LUPEROX^® 554M75

Luperox® 554M75 polymer initiator is a t-amyl peroxyester for the polymerization of vinyl chloride or acrylic monomers. Using Luperox® 554M75 will help reduce the formation of fish-eye voids in PVC resins as polymerization kinetics are better controlled. For acrylic polymerization, the recommended process temperature is 50° to 80°C. t-Amyl peroxyesters are very efficient and generate lower energy radicals that can narrow polydispersity in acrylic resins and yield lower overall solution viscosity
