Abstract
A 2-cyanoethyl-containing organoxysilane compound having the formula: NC—CH2—CH2—X—Si(OR1)3 is heat resistant and compatible with organic solvents. R1 is a C1-C20 monovalent hydrocarbon group, and X is a C2-C20 divalent hydrocarbon group which contains a methylene and/or methine moiety, at least one of the methylene and methine moieties being substituted with a divalent heteroatom linking moiety NR (wherein R is hydrogen, C1-C20 monovalent hydrocarbon group or 2-cyanoethyl), a trivalent heteroatom linking moiety N, or a combination thereof.
