PROBLEM TO BE SOLVED: To provide a process for preparing organyloxysilyl-terminated polymers which have increased stability toward atmospheric moisture, and crosslinkable compositions including such polymers. SOLUTION: The process for preparing organyloxysilyl-terminated polymers which have increased stability toward atmospheric moisture is provided by reactingα,ω-dihydroxy-terminated organic polymers with isocyanate-functional silanes in the presence of at least one catalyst selected from the group consisting of bismuth and zinc compounds.
