Abstract
Abstract A method for adhering an organic substance to a metallic or inorganic oxidic substance which comprises disposing between said organic substance and said metallic or inorganic oxidic substance a phosphorus organosilane of the general formula WHEREIN EACH R is independently a substituted or unsubstituted aliphatic radical, each A is a bivalent alkylene or arylene radical or a bivalent oxyalkylene or oxyarylene radical joined by its oxygen to the phosphorus atom, m, n, p and x are each values of 0 or 1, B is either a bivalent oxygen radical, an -NHradical, an -NR- radical or an -S- radical when p is equal to 1 and y is equal to 1 to 20.
