Abstract:
A curable resin composition which comprises(I) a reactive silicon group-containing polyether oligomer such that the reactive silicon group exists exclusively at the molecular chain terminus and that the introduction rate of the reactive silicon group into the molecular terminus is not less than 90% as determined by 1H-NMR analysis, and (II) a reinforcing filler, wherein the reactive silicon group-containing polyether oligomer (I) is obtained by reacting (a) a polyether oligomer the main chain of which comprises a polyether and which contains at least one unsaturated group represented by the general formula (2) or the general formula (3): H2C&boxH;C(R3)â€”R4â€”Oâ€”â€ƒâ€ƒ(2) HC(R3)&boxH;CHâ€”R4â€”Oâ€”â€ƒâ€ƒ(3) â€ƒwherein R3 represents a hydrocarbon group containing up to 10 carbon atoms and R4 represents a divalent organic group containing 1 to 20 carbon atoms and at least one member selected from the group consisting of hydrogen, oxygen and nitrogen as a constituent atom, per molecule, with (b) a reactive silicon group-containing compound in the presence of (c) a group VIII transition metal catalyst.
