Patent ID: 8101098

Claim:
Flowable additive comprising an Si-activable, oligomeric azomethinesilane component A) and an azomethine component B) in a molar ratio of 100:0.1 to 1:1, with a fraction totalling >5% by weight, the Si-activable, oligomeric azomethinesilane component A) being prepared by reacting an aminosilane c) of the general formula R 1 R 2 R 3 Si—(CH 2 ) n —(CR 4 R 5 )—(CH 2 ) n —NH—R 6 (I) where n=1; R 4 and R 5 each=H; R 1 and R 2 each independently of one another =C 1 -C 18 n-alkyl; R 3 =OR 7 ; R 7 =C 1 -C 6 n-alky; R 6 =H, with formation of water and an Si-activable monomeric azomethinesilane component as intermediates, with a carbonyl compound d) of the general formula R 11 —CO—R 12 (II) where R 11 =C 1 -C 30 n-alkyl; R 12 =C 1 -C 30 n-alkyl; with the proviso that per mole of aminosilane c) employed there are 0.6 to 1.2 mol of the water intermediate formed available for the oligomerization—which consumes water as a reaction component—of the Si-activable monomeric azomethinesilane component produced as intermediate, and the azomethine component B) is described by the general formula X—N=CR 21 R 22 (III) where R 21 =H; R 22 =C 1 -C 30 n-alkyl; X=C 1 -C 18 n-alkyl, having 1 to 3 alike or different —N═CR 21 R 22 substituents.
