The use of high-temperature-resistant random block copolycondensates comprising at least two different diols of the formula I <IMAGE> and dihalogen compounds of the formula II <IMAGE> or ring-substituted chloro, fluoro, aryl, C1-C6-alkyl or alkoxy derivatives thereof, for the production of circuit boards and electrical plug connections, where X is a chemical bond, -O-, -S-, <IMAGE> , Y1 and Y2 are Cl or F, Q and W are <IMAGE> , Z is -O- or a chemical bond, R<1> and R<2> are alkyl or alkoxy groups having 1-6 carbon atoms, Cl, F or aryl groups, and R<3> and R<4> are hydrogen atoms, alkyl groups having 1-6 carbon atoms, alkoxy groups having 1-6 carbon atoms or aryl groups, and m has the value 0 or 1, n and p have the value 0, 1, 2, 3 or 4, and k and q have the value 0 or 1.
