ABSTRACT:
A novel peroxy aryl carbonate which has the both properties of polymerization-initiating and regulating abilities, can be used as a radical polymerization initiator to regulate the polymerization rate, the polymerization degree and molecular weight distribution of the polymer and the like, and therefore produce superior styrene resin and methyl methacrylate syrup.
