POLYMERIZATION OF STYRENE BY DIPHENYLZINC-ADDITIVE SYSTEMS. PART X. HOMO- AND COPOLYMERIZATION OF STYRENE USING Ph2Zn - METALLOCENE - MAO SYSTEMS

Combination of diphenylzinc, Ph2Zn, cyclopentadienyl titanium trichloride, CpTiCl3, and methylaluminoxane, MAO, were used to initiate styrene, S, polymerization and its copolymerization with 1-hexadecene, 1-C16H32, and with p-tert-butylstyrene, p-ButS. For homopolymerization an almost pure syndiotat...
