| titleOfInvention | A thermotropic liquid crystal polymer and its application in PC resin |
| abstract | The present invention provides a thermotropic liquid crystal polymer, wherein the thermotropic liquid crystal polymer is an alkylated polybutylene terephthalate/parahydroxybenzoic acid copolyester, an alkylated polyparaphenylene The preparation method of butylene terephthalate/p-hydroxybenzoic acid copolyester comprises the following steps: adding polybutylene terephthalate/p-hydroxybenzoic acid copolyester into the alkylating agent solution, and ultrasonically treating 5 ~60min, filtered, washed with water until neutral, and dried to obtain alkylated polybutylene terephthalate/parahydroxybenzoic acid copolyester. Adding the thermotropic liquid crystal polymer to the PC resin can improve the melt processability of the PC and solve the problem of cracking of the lamp body caused by the internal stress concentration of the PC resin during the extrusion process. |
