Abstract:
1. A method for making a oligomeric silsesquioxane (OS)-diamine aromatic compound having the general formula, comprising: wherein R are organic substituents, R dissolving a oligomeric silsesquioxane (OS)-diamine aromatic compound having the general formula, wherein R is organic substituents, R1 is an alkyl or aromatic organic linker, X is selected from the group consisting of NH, NR, and Ar is a mono- or poly-aromatic system, n is an integer ranging between 6 and 12; adding an aliphatic tertiary amine to the said solution of said amino-functional oligomeric silsesquioxane compound; homogenizing said solution of said amino-functional oligomeric silsesquioxane compound; adding a solution of an aromatic di-nitro acid chloride to said solution of said amino-functional oligomeric silsesquioxane compound; allowing the mixture to remain homogeneous and in contact for and effective amount of time sufficient to complete the conversion of acid chloride and amine groups to amide groups forming a compound with the general formula (RSi) dissolving said (RSi) adding platinum dioxide or transition metal hydrogenation catalysts under an atmosphere of hydrogen at pressures of 1 to 1000 psig; and allowing contact of reactants until hydrogenation is substantially complete to formulate said diamine (C).
