Poly propylene-co-p-

The poly[propylene-co-p-(3-butenylstyrene)] (PP-BSt) copolymers were prepared by a specific rac-CH2(3-t-butyl-Ind)2ZrCl2 catalyst that exhibits highly favorable reactivity toward a-olefin over styrene moieties [48]. In other words, most of the BSt comonomers are incorporated through the a-olefin moiety. The incorporated BSt unit results in a pendant styrene moiety in the copolymer. Table 6 summarizes a set of PP-BSt copolymers. The appearance of the reacting polymer solution was dependent on the quantity of BSt used. In the high BSt case (run VI-7),...
