Abstract

PURPOSE: To obtain the titled compound in a short time readily in high yield useful as a coupling agent, by reacting an isocyanic acid compound obtainable at inexpensive price with an amino group-containing alkoxysilane.
CONSTITUTION: A compound (e.g., 3-aminopropyltrimethoxysilane) shown by the formula I (R1 is alkyl; R2 is monofunctional hydrocarbon group; a is 0, 1, or 2; n is 1W6) is reacted with an isocyanic acid compound (e.g., methylisocyanate) shown by the formula R3NCO (R3 is H or 1W10C monofunctional group) in a temperature range of -75W150°C, preferably -50W120°C, to give the titled compound shown by the formula II. A compound wherein R3 is alkyl, aryl, etc. among the compound shown by the formula II exhibits improved coupling effect in the composite system consisting of a silicon inorganic material and a synthetic resin.
