| titleOfInvention | A kind of preparation method of liquid crystalline polymers |
| abstract | The invention discloses a kind of preparation method of liquid crystalline polymers; described liquid crystalline polymers comprises the structural unit derived from P-hydroxybenzoic acid (I) of 40-80mol%, the structural unit (II) of 10 ~ 30mol% and the structural unit (III) of 10 ~ 30mol%; comprise the following steps: under the existence of acylating agent and phosphite ester compound, make the monomer of the structural unit represented containing formula I, (II) and (III) respectively carry out acylation reaction and transesterification reaction prepares liquid crystalline polymers.Liquid crystalline polymers of the present invention does not need to add stablizer by melt blending and carries out modification, it introduces phosphite ester compound in building-up process, the liquid crystalline polymers self prepared is made just to have good heat-resistant stability, and carrying out in the composite or molding process of filler, even if be exposed to high temperature also can not produce black impurity, can be used for preparing moulded product. |
