Description

Peroxydicarbonic acid, C,C’-ditetradecyl ester (CAS No. 53220-22-7), also known as Dimyristyl peroxydicarbonate, is a high-purity organic peroxide widely used as a polymerization initiator in industrial applications. With the molecular formula C₃₀H₅₈O₆, this technically pure compound is characterized by its stability, efficiency, and controlled decomposition properties, making it ideal for free-radical polymerization processes. It is supplied as a fine white powder or flakes, ensuring uniform dispersion and consistent performance in polymer synthesis. Suitable for use in both bulk and suspension polymerization, this peroxydicarbonate derivative is particularly effective in the production of PVC, polystyrene, and other vinyl-based polymers. Strict storage and handling protocols are recommended due to its thermally sensitive nature.

Dimyristyl peroxydicarbonate serves as a highly efficient initiator for the polymerization of vinyl monomers, including PVC and polystyrene, due to its controlled decomposition at moderate temperatures. It is commonly used in bulk and suspension polymerization processes to achieve high molecular weight polymers with uniform properties. This compound is favored in industrial settings for its ability to produce clear, high-quality polymer products with minimal residual impurities. Proper temperature regulation is essential to optimize its performance and ensure safe handling during polymerization reactions.
