Abstract
Thermoplastically processable thermotropic molding compounds of thermotropic polycondensates and 0.05 to 5% by weight functionalized polymers, such as for example functionalized polybutadiene oils, polyethylene or polypropylene.
Claims20
A thermoplastically processable molding compound consisting of:
- A) a thermotropic polycondensate containing the following structural units:
- a) 40-85 mol % aromatic hydrocarboxylic acid units;
- b) 0-40 mol % aminocarboxylic acid units;
- c) 15-60 mol % of diphenol units and/or aliphatic diol units;
- d) 0-25 mol % aminophenol units;
- e) 15-60 mol % aromatic dicarboxylic acid units and/or aliphatic dicarboxylic acid units;
- and
- f) 0-30 mol % carbonic acid units or carbonic acid derivative units;
- B) 0.02 to 2% by weight, based on 100% by weight of A, of a functionalized polymer comprising a copolymer of:
- a) 40 to 100% by weight of at least one alpha olefin containing 2-8 carbon atoms;
- b) 0 to 50% by weight of a diene;
- c) 0 to 45% by weight of a primary or secondary C.sub.1-12 alkyl ester or acrylic or methacrylic acid or mixtures of such esters;
- d) 0 to 45% by weight of an olefinically unsaturated mono- or dicarboxylic acid, which may be completely or partially in salt form, or a functional derivative thereof;
- and
- e) 0 to 40% by weight of an epoxyfunctional monomer;
- and
- C) optionally, reinforcing materials, fillers, pigments, or dyes.

- b) an aromatic aminocarboxylic acid;
- c) a diphenol and/or an aliphatic diol;
- d) an aminophenol;
- e) an aromatic and/or aliphatic dicarboxylic acid;
- and
- f) a carbonic acid or carbonic acid derivative, with
- B) about 0.02 to 2% by weight, based on 100% by weight of the liquid crystalline polymer, of a functionalized polymer comprising a copolymer of:
- a) 40 to 100% by weight of at least one alpha olefin containing 2-8 carbon atoms;
- b) 0 to 50% by weight of a diene;
- c) 0 to 45% by weight of a primary or secondary C.sub.1-12 alkyl ester or acrylic or methacrylic acid or a mixture of the esters;
- d) 0 to 45% by weight of an olefinically unsaturated mono- or dicarboxylic acid, which may be completely or partially in salt form, or a functional derivative thereof;
- and
- e) 0 to 40% by weight of an epoxy functional monomer,
- wherein B contains along a main polymer chain, reaction terminal groups or corresponding groups, selected from the group consisting of double bonds, triple bonds, amino groups, glycidyl groups, hydroxy groups, carbonate groups, amide groups, carboxy groups, ester groups, anhydride groups and urethane groups.
