Aromatic compounds of formula I
Z Ph′ X Ph Y Ar Y Ph X Ph′ Z I
where
X is selected from -CO-, -SO- or -SO₂-;
Y is selected from -O- or -S-;
Z is -NH₂ or a maleimide radical;
Ar is a phenylene unit or a polyaromatic group containing at least two aromatic units which are either linked directly together or are linked by a class selected from -CO-, -SO-, -SO₂-, -O-, -S-, -C(CH₃)₂ and other aliphatic groups;
Ph is 1,4-phenylene; and
Ph′ is 1,3-phenylene when Z is -NH₂ and Ph′ is 1,3 - or 1,4 - phenylene when Z is a maleimlde radical.
Polymers comprise a repeat unit of formula
- D - Z³ -
where D is a divalent aromatic radical derived from a compound of formula I, in which Z is -NH₂ and Ph′ is 1,3-phenylene, and Z³ is
where Ar′ is a tetravalent aromatic radical derived from a dianhydride or a corresponding derivative thereof. Up to 50 mole % of the radicals D can be replaced by divalent organic radicals derived from diamines other than those falling within formula I.
