A BrønstedLowry acid initiator system for cationic polymerization of an ethylenically unsaturated monomer involves an initiator having a structure of Formula (I) in an anhydrous polymerization medium (I) where: M is tantalum (Ta), vanadium (V) or niobium (Ni); each R1 is independently H, OR6, F, Cl, Br, I or alkyl, where R6 is H or alkyl; R2, R3, R4 and R5 are independently H, F, Cl, Br, I, alkyl or aryl, or two or more of R2, R3, R4 and R5 on a same benzene ring form a bicyclic, tricyclic or tetracyclic moiety with the benzene ring, with the proviso that all of R2, R3, R4 and R5 on the same benzene ring are not H; L is absent or a molecule that coordinates to H+; and, x is 0 when L is absent, or x is 0.5 or more when L is present.
一种Brønsted-Lowry酸引发剂体系用于烯丙基不饱和单体的阳离子聚合,包括在无水聚合介质中具有式(I)结构的引发剂(I):其中,M为钽(Ta)、钒(V)或铌(Ni);每个R1独立地为H、OR6、F、Cl、Br、I或烷基,其中R6为H或烷基;R2、R3、R4和R5独立地为H、F、Cl、Br、I、烷基或芳基,或者在同一苯环上的两个或更多个R2、R3、R4和R5形成一个双环、三环或四环的基团与苯环结合,但同一苯环上的所有R2、R3、R4和R5不是H;L不存在或是一个与H+配位的分子;x在L不存在时为0,在L存在时x为0.5或更大。
