The coordination polymerization of silyl-protected ω-alkenols such as ω-alken-α-oxytriisopropylsilanes 1 provides poly(ω-alkenyl-α-oxytriisopropylsilalne)s with a highly isospecific microstructure ([mmmm] > 95%) when a combination of [OSSO]-type bis(phenolato) dichloro zirconium(IV) complex 2 and dried methylaluminoxane is used as the precatalyst and activator, respectively. The resulting siloxy-substituted polymers could be efficiently transformed into the corresponding functionalized polyolefins, which contained up to 90% acetyl groups and ≈7% hydroxy groups in the terminal side chains.
当使用[OSSO]型双（酚氧基）二氯锆（IV）配合物2和干燥的甲基铝氧烷分别作为预催化剂和活化剂时，甲硅烷基保护的ω-链烯醇（如ω-链烯-α-氧基三异丙基硅烷1）的配位聚合可提供具有高度等规微观结构（[mmmm]＞95%）的聚（ω-链烯基-α-氧基三异丙基硅烷）。所得的硅氧基取代聚合物可有效地转化为相应的功能化聚烯烃，其末端侧链中含有高达90%的乙酰基和约7%的羟基。
