Organosilane- and/or organosiloxane-containing agent used in filled polyamide

Abstract

Organosilicon-based materials for the surface modification of fillers comprise: (A) amino-functional silanes, (B) mixtures of aminofunctional silanes and alkyl-, alkenyl- or polyether-functional silanes or (C) mixtures of alkyl- and alkenyl-functional silicon compounds (or their hydrolysis/condensation products in each case). Organosilane- and/or organosiloxane-containing materials (A, B and C) for the surface modification of fillers used in the production of filled polyamides comprise: (A) an amino-functional compound of formula (I) or bis-aminosilane(s) or tert. aminosilane(s) or a mixture of prim. and sec. and/or tert. aminosilanes (and/or tert. aminosiloxanes with an average degree of oligomerization (DO) of 2-20) obtained by hydrolysis and (co)condensation of corresponding aminosilanes, or (B) (i) amino-functional compound(s) of formula (II), and/or sec. aminosilane(s) and/or tert. aminosilane(s) and (ii) alkyl-, alkenyl- or polyether functional silicon compound(s) of formula (III), (IV) or (V) respectively, and/or (iii) optional siloxanes with a DO of 2-20 obtained by hydrolysis and (co)condensation of compounds (II), sec. or tert. aminosilanes, bis-aminosilanes, or compounds (III), (IV) or (V), or (C) (i) compound(s) (III) and (ii) compound(s) (IV) and/or optional siloxanes with a DO of 2-20 obtained by hydrolysis and (co)condensation of (III) and (IV). R-NH-(CH2)3-Si(CH3)x(Z)3-x (I) Z = 1-3C alkoxy, hydroxy or chlorine; x = 0 or 1; and R = 1-20C alkyl, 5-12C cycloalkyl or 6-12C aryl. R-Si(CH3)x(Z)3-x (II) R'-Si(CH3)x(Z)3-x (III) CH2=CH-(CH2)n-Si(CH3)x(Z)3-x (IV) R-(O-CH2CHR')n-O-(CH2)m-Si(CH3)x(Z)3-x (V) R = a group of formula H2N-((CH2)2NH)y-(CH2)3- (in II), or 1-4C alkyl (in V); y = 0, 1 or 2; R' = optionally fluoro-substituted 1-16C linear, branched or cyclic alkyl (in III), or H or methyl (in V); n = 0-20 (in IV) or 5-20 (in V); and m = 2 or 3 Independent claims are also included for: (a) surface-modified fillers obtained by treatment with these materials; (b) articles containing these fillers; (c) filled polyamide containing these fillers; (d) articles based on these filled polyamides.
