Abstract

ABSTRACT Cationic ring-opening polymerizations of 5-alkyl-or 5, 7-dialkyl-1, 3- dehydroadamantanes, such as 5-hexyl-(4), 5-octyl-(5), 5-butyl-7-isobutyl-(6), 5-ethyl-7-hexyl- (7), and 5-butyl-7-hexyl-1, 3-dehydroadamantane (8), were carried out with super Brønsted acids, such as trifluoromethanesulfonic acid or trifluoromethanesulfonimide in CH 2 Cl 2 or n- heptane. The ring-opening polymerizations of inverted carbon–carbon bonds in 4–8 ...
