摘要:
Polymer compositions exhibiting liquid-crystalline phases contain chemically bonded mesogenic groups of the formula Ia and/or Ib: ##STR1## in which Q.sup.1 is H, alkyl or alkoxy having 1-5 C atoms, F, Cl, Br or CN,X.sup.1 to X.sup.5 each, independently of one another, are H or an alkyl group having up to 15 C atoms, in which it is also possible for one or two non-adjacent CH.sub.2 groups to be replaced by a group from the group comprising --O--, --S--, --O--CO--O--, O--CO--NH--, --CO--, --CO--O--, --CO--S--, --S--CO--, --SO-- and --SO.sub.2 --.Process for the preparation of polymer compositions of this type comprises the polymerization or grafting of suitable monomers.Polymer compositions of this type are used as substrates in electronics for the fiber and foil techniques.
