Abstract

Abstract Translated from German Verzweigte, hochmolekulare, thermoplastische, Nitrilgruppen enthaltende Polyarylenether, aufgebaut aus wiederkehrenden Einheiten der Formel I in der E, einen Rest bezeichnet, der sich von Dihalogenbenzolverbindungen ableitet und die E 2 einen Rest bedeutet, der sich von Bisphenolen ableitet und Verzweigungsmitteln, gekennzeichnet durch einen Gehalt von 0,01 bis 5 Mol-%, bezogen auf den Rest E 1 an mindestens einem Rest, der sich von Polyhalogenverbindungen der Formeln in denen X für ein Fluor oder Chloratom steht, ableitet, sowie deren Herstellung. Branched, high molecular weight, thermoplastic, nitrile group-containing polyarylene ethers, built up from recurring units of the formula I. in which E denotes a radical which is derived from dihalobenzene compounds and which E 2 is a radical which is derived from bisphenols and branching agents, characterized by a content of 0.01 to 5 mol%, based on the radical E 1 at least one residue that differs from polyhalogen compounds of the formulas in which X represents a fluorine or chlorine atom, and their preparation.
