Abstract (en)
[origin: EP1544204A1] New aldiminoalkylsilanes (I) are reaction products of aminoalkyl-trialkoxy-, -dialkoxyalkyl- or alkoxydialkyl-silane(s) (II) and aldehyde(s) (III) with a tertiary carbon atom in the alpha -position to the aldehyde carbonyl group. New aldiminoalkylsilanes (I) are reaction products of aminoalkyl-trialkoxy-, -dialkoxyalkyl- or alkoxydialkyl-silane(s) of formula (II) and aldehyde(s) of formula (III), which have a tertiary carbon atom in the alpha -position to the aldehyde carbonyl group: H 2N-R 1>-Si(R 3>) a(OR 2>) 3 - a (II); O=CH-C(Y 1>)(Y 2>)(Y 3>) (III); R 1>linear or branched, optionally cyclic 1-20 C alkylene, optionally with aromatic components and/or heteroatom(s), especially N atom(s); R 2>1-5 C alkyl; R 3>1-8 C alkyl; a : 1, 2 or especially 0; Y 1>, Y 2>organic groups or together a 5-8-, preferably 6-membered carbocyclic or heterocyclic ring; Y 3>(substituted) alkyl containing heteroatom(s), branched or linear alkyl(ene) with not less than 10 C, (substituted) aryl or arylalkyl, O-R 4>, O-C(=O)-R 4>, C(=O)-O-R 4> or C(=O)-R 4>; R 4>(substituted) alkyl, arylalkyl or aryl with not less than 3 C. Independent claims are also included for the following: (1) preparation of (I); (2) (I) hydrolysis processes; (3) moisture-curing polyurethane composition.
