Abstrael--.By analytical determination of peroxides of powdered isotactic polypropylene capable of initiating polymerization in an emulsion system at 30 ¢, it was proved that binding of styrene on polypropylene occurs only when the polymerization activator (e.g. chelate FeSO,,-triethylenetetramine)

A monomer mixture of styrene (St) and maleic anhydride (MA) was grafted on isotactic polypropylene (PP) powder at 80°C in benzene. During that process ungrafted copolymer is formed at the same time. The initiators are peroxide groups formed on the surface of polypropylene (PP) by ozonization or by g
