ABSTRACT:
The present invention relates to a process for preparing organyloxysilyl-terminated polymers which have increased stability toward atmospheric moisture, by reacting hydroxy-terminated organic polymers with isocyanato-functional silanes in the presence of at least one catalyst selected from the group consisting of bismuth and zinc compounds, and to crosslinkable compositions comprising such polymers.
