• Binary copolymerization of styrene, allyltri-methylsilane and 3-butenyltrimethylsilane was investigated using the Ziegler catalyst at 70°C. It was found to be possible to separate the crystalline part of copolymers by fractional extraction into two kinds of genuine crystalline copolymers, each of which has an extremely different composition from the other.<BR>The nature of the active sites on the catalytic surface was discussed in order to elucidate the above fact.<BR>The constitution of the individual crystalline fractions appeared to vary case by case, i.e., the structure of blockcopolymer might be assigned to some cases and random copolymers to some other cases.
