Polymer mixture containing alkoxysilane-terminated polyether or polyurethane and alkoxysilylalkyl-substituted succinic anhydride, used in adhesives, sealants and joint fillers

摘要

Polymer mixtures based on alkoxysilane-terminated polymers and also containing alkoxysilylalkyl-substituted succinic anhydrides. Polymer mixtures (I) containing (A) alkoxysilane-terminated polymers with at least one end group of formula -A-(CH 2) m-Si(R 1) a(OR 2) 3-a (1) and (B) succinic anhydride-alkoxysilanes of formula (2). A : -O-, -S-, -NR 3-, -OCONR 3-, -NR 3COO-, -NR 3CONH-, -NHCONR 3- or -NR 3CONR 3-; R 1optionally halogenated 1-10C alkyl, cycloalkyl, alkenyl or aryl; R 21-6C alkyl or 2-10C omega -oxoalkyl-alkyl; R 3H, optionally halogenated 1-18C alkyl,or alkenyl (cyclic, linear or branched), or 6-18C aryl; a : 0-2; m : 1-6; R 4H or 1-6C alkyl; R 5as for R 1; R 6as for R 2; n : 1-6; b : 0-2 .An independent claim is included for a method for the production of mixtures (I) which also contain (C) aminoalkyl-alkoxysilane, by making a mixture of polymer (A) and filler, adding component (B) and then adding (C).
