Abstract
Abstract Novel alkoxysilane cluster compounds are described having the formula: <IMAGE> wherein n is an integer from 0 to 300; R is hydrogen, alkyl, alkenyl, aryl, aralkyl or -OSi(OR')3; each R' is independently selected from alkyl, alkenyl, aryl or aralkyl with the proviso that at least a majority of R' radicals are sterically hindered alkyl groups having at least 3 carbon atoms; and R'' and R''' are independently selected from hydrogen, alkyl, alkenyl, aryl, aralkyl, hydroalkyl, and halo or cyano substituted alkyl, alkenyl, aryl, aralkyl, and hydroalkyl. The preparation and use of these alkoxysilane cluster compounds also are described.
