Abstract
Copolymers comprising recurring units (A) of one or more of the general structural formulae -D-G-Ar-G-, -G-D-G-Ar- and/or -D-G- on one hand, and recurring units (B) of one or more of the general structural formulae —Ar-G-Ar-G-, -G-Ar-G-Ar- and/or —Ar-G- on the other hand, wherein D is a dibenzodiazocine-containing divalent group, Aris a dibenzodiazocine-free divalent group containing a sulfone unit and/or a ketone unit, Aris a dibenzodiazocine-free divalent group, and G is an ether or a thiether group. Preferably, recurring units (A) are of the general structural formula -D-G-Ar-G- and recurring units (B) are of the general structural formula —Ar-G-Ar-G-. Method for the preparation of the copolymers, compositions and articles made of the copolymers are also part of the invention.
