COPOLYMERIZATION OF STYRENE BY DIPHENYLZINC-ADDITIVE SYSTEMS: PART III. COPOLYMERIZATION OF STYRENE/para- METHYLSTYRENE USING CpTiCl3-MAO and Ph2Zn-CpTiCl3-MAO INITIATOR SYSTEMS

The copolymerization of styrene with p-methylstyrene has been tested using combined diphenylzinc-additive initiator systems, including diphenylzinc, Ph2Zn, a metallocene: cyclopentadienyltitanium trichloride, CpTiCl3, and methylalumoxane, MAO, as well as the binary CpTiCl3-MAO initiator system. Both...
