A copolymer is described which is prepared by reacting a polyphenylene having two terminal coupling groups X
1
and X
2
with a flexible chain component which has a flexible chain having two terminal coupling groups Y
1
and Y
2
. A high modulus of elasticity, high media resistance, and cost-effective, large-scale production may be achieved in that the flexible chain has a chain length of less than or equal to
95
chain atoms, and each of coupling groups X
1
and X
2
reacts with one of coupling groups Y
1
and Y
2
, forming a bond selected from the group composed of carboxylic acid amide, carboxylic acid ester, carboxylic acid imide, urethane, carbonate, urea, thiourea, sulfonic acid amide, sulfonic acid ester, imidazole, oxazole, thiazole, oxazoline, imidazoline, amine, ether, and thioether bonds.
