  • Polymer composition on the basis of polymer and a polyester amide
    Patent number: 4988776
    Abstract: The invention relates to a melt-processible aromatic (co)polymer composition containing:1-99 wt. % of a liquid crystalline polymer, and99-1 wt. % of a polymer derived from units, capable of forming a liquid crystalline polymer, and from one or more triazine units according to the formula (I) ##STR1## where R.sub.1 is an amino group, R.sub.2 and R.sub.3 is an (alkyl)carboxyl-, an (alkyl)hydroxy- and/or an amino group.Besides excellent mechanical properties, the (co)polymer composition according to the invention possesses an improved thermal shock resistance. The (co)polymer composition is eminently suited for use in objects for the electrical industry and the aircraft industry.

  • Aromatic polyester
    Patent number: 4876327
    Abstract: The invention relates to aromatic polyesters containing units with two carbonyl groups and having liquid crystalline properties. The aromatic polyesters are characterized in that the polyesters contain heterocyclic units with two carbonyl groups. Preferably these units are derived from furandicarboxylic acid. The aromatic polyesters show a considerable reduction in melting temperature, rendering the polyester more processable.
