摘要：

Adducts of B(C(6)F(5))(3) with the series of long chain carboxylic acids CH(3)(CH(2))(n)CO(2)H (n = 2,4,6,8,10,12,14,16,18,20) are assessed for their abilities to initiate the carbocationic polymerization of isobutene. It is found that the adducts behave in MeCl/CH(2)Cl(2) as strong acids with very weakly coordinating counteranions, inducing the rapid formation in high conversions of ultrahigh molecular weight polyisobutene (M(w) similar to 2 x 10(6) g/mol, M(w)/M(n) similar to 1.5) at -50 degrees C.
