Heptaisobutyl-norbornenylethyl-substituted cage octasilsesquioxane (POSS) (1a)
and heptaphenyl-norbornenylethyl-substituted POSS (1b) were subjected to
ring-opening metathesis polymerizations (ROMP) at room temperature with the
Grubbs 2nd generation catalyst. The metathesis polymerizations of 1a and 1b were
performed at room temperature for 3 h with initial monomer molar concentrations
of [1a, 1b]... hiện toàn bộ
