    • The present invention provides a reactive silicon group-containing polymer containing at least one reactive silicon group per molecule, the main chain of the polymer being essentially a copolymer of organopolysiloxane and polyoxyalkylene, which causes no macro phase separation during storage and gives a hardened material having an excellent weathering resistance, little residual tack and excellent coating adhesivity. The present invention provides a process for the preparation of the foregoing reactive silicon group-containing polymer. A novel process for the preparation of the polymer as defined above is provided, which comprises allowing an alkylene oxide to undergo ring opening polymerization with an organopolysiloxane compound having an active hydrogen-containing functional group with which said alkylene oxide is reactive as an initiator in the presence of a catalyst to synthesize a polymer of organopolysiloxane and polyoxyalkylene, and then introducing a reactive silicon group into said polymer. Another process for the preparation of the polymer as defined above is provided, which comprises allowing an alkylene oxide to undergo ring opening polymerization with an organopolysiloxane compound having an epoxy group in the presence of a catalyst with an active hydrogen-containing compound as an initiator to synthesize a polymer the main chain of which is essentially a copolymer of organopolysiloxane and polyoxyalkylene, and then introducing a reactive silicon group into said polymer.
