Preparation of oligomeric silsesquioxane compounds, useful for the modification of polymers, by direct base catalysis of the corresponding silicon compound using a specific initial ratio of compound to base
Oligomeric silsesquioxane compounds are prepared directly by base catalysis of the corresponding silicon compound, using an initial ratio of compound to base of 500:1-3:1. Oligomeric silsesquioxane compounds of formula R1aR2bR3cR4dR5eR6fR7gR8hO12 and structure (I) are prepared directly by base catalysis of RSiX3 , where the ratio of RSiX3 to base at the beginning of the reaction is 500:1-3:1. R, R1-R8 = optionally substituted (cyclo)alkyl, (cyclo)alkenyl, (cyclo)alkynyl, (hetero)aryl or H; X = a hydrolyzable or condensable group; and a+b+c+d+e+f+g+h = 8.
