Abstract: Process for the preparation of poly(diorganosiloxanes) with alkoxy end groups A process for the preparation of triorganyloxysilylor diorganyloxyorganosilyl-terminated poly(diorganosiloxanes) or formulations containing such siloxanes comprising reacting .alpha.,.omega.-dihydroxypoly(diorganosiloxanes) with tetraorganyloxysilanes or triorganyloxyorganosilanes in the presence of an ammonium carbamate catalyst of the formula I (I) wherein, R represents a hydrocarbon radical with 1 - 20 C atoms or an H atom, and where identical or different R radicals are in the molecule. The products produced by this process can be employed in the preparation of one-component silicone paste which harden into elastomers in the presence of moisture. Le A 23 856
