MOULDING MATERIAL ON THE BASIS OF POLYARYLENE ETHERS AND POLYAMIDES

摘要

The invention relates to moulding material containing A) at least one modified polyarylene ether having carboxyl groups and recurring units of formulas (I) and (II), where x is 0.5 or 1, t and q independently of each other are 0, 1, 2, or 3, n is a whole number between 0 and 6, Q, T, Y and Z independently of each other are one chemical bond or group each, selected from among -O-, -S-, -SO2-, S=O, C=O, -N=N-, -RC=CR- and -CRR-, where R and R independently of each other each represent a hydrogen atom or a C1-C12 alkyl group and R and R independently of each other each represent a hydrogen atom or a C1-C12 alkyl-, C1-C12 alkoxy-, or C6-C18 aryl group, where R and R independently of each other can be substituted with fluorine and/or chlorine atoms or, together with the C-atom to which they are bonded, can form a C3-C12 cycloalkyl group which can be substituted with one or more C1-C6 alkyl groups, provided that at least one of the T, Q and Z groups represents -SO2- or C=O and that if t and q are 0, Z is -SO2- or C=O; Ar, Ar<1>, Ar<2> and Ar<3> independently of each other represent C6-C18 arylene groups which, if desired, are substituted with C1-C12 alkyl-, C6-C18-aryl-, C1-C12-alkoxy groups or halogen atoms; R<1> is H, C1-C6-alkyl or -(CH2)n-COOH; and the molar ratio of units of formula (I) to units of formula (II) ranges from 0.05: 99.95 to 99.95: 0.05; B) if desired at least one polyarylene ether with anhydride groups (b1) or a polyarylene ether with epoxy groups (b2) or a mixture of (b1) and (b2); C) at least one polyarylene ether with end groups which differ from those of the polyarylene ethers B); D) at least one polyamide and E) at least one toughened caoutchouc with groups reactive in relation to carboxyl groups (e1) or a mixture of (e1) and at least one toughened caoutchouc which does not contain any groups reactive in relation to carboxyl groups (e2).
