The invention relates to an aromatic polymer processable from the melt and showing anisotropic behaviour, which polymer contains a triazine unit according to formula I:
where Y1 and Y2 are the same or different and comprise an (alkyl)carboxy, an (alkyl)hydroxy or an amino group, where R = hydrogen, alkyl radical with 1-4 C atoms, cycloalkyl radical with 3-6 C atoms, allyl radical, aryl radical or halogen, and
m = 1 or 2;
n = 0 or 1, if n = 1
then: X = -O-, -SO2- or -N=;
or (X)n-(R)m is a group according to any one of formulas II:
The polymer according to the invention has, in addition to a good thermal shock resistance, excellent mechanical properties and will mainly be used in the electrical engineering, the aircraft industry, the automative industry and for the production of ovenware.
