Abstract
The invention relates to a copolycarbonate with high flow and high chemical resistance, comprising the following structure: from compounds containing a structure as shown in formula (1)
The structural unit of (4); from compounds containing multiple benzene ring structures
Description
Technical Field
The present invention relates to a copolycarbonate, and more particularly, to a copolycarbonate having high flow and high chemical resistance.
Background introduction
Polycarbonates are known to be stable and transparent thermoplastic resins and have high impact resistance. However, polycarbonates also have a relatively high melt viscosity. Therefore, in order to produce molded products using polycarbonate, relatively high extrusion temperatures and molding temperatures are required. Over the years, considerable efforts have been made to reduce the melt viscosity of polycarbonates while maintaining better physical properties. For this, using a plasticizer, using an aliphatic chain terminator, reducing the molecular weight, or preparing a resin having a long chain aliphatic group when an aliphatic chain terminator is used, fluidity can be easily and correctly obtained, but impact resistance measured using a notched cantilever beam is remarkably deteriorated. Furthermore, brittleness can be problematic. When a bisphenol having an aliphatic long chain is used, an increase in fluidity can be observed. However, this is usually accompanied by a significant reduction in the desired impact strength properties.
Chinese patent CN 112409586A describes a process for preparing high flow polycarbonate by adding excess aqueous sodium hydroxide solution to saturated dibasic fatty acid to prepare saturated dibasic fatty acid sodium salt, mixing saturated dibasic fatty acid sodium salt with bisphenol a, process water and solvent, and introducing phosgene to the mixture to react. The method relates to a highly toxic gas phosgene which has high danger and is difficult to obtain.
Chinese patent CN201711272381.9 describes a high-flow, chemical-resistant polycarbonate and a preparation method thereof, in which a thermoplastic polyester elastomer and ABS are added to the polycarbonate to improve the chemical resistance of the polycarbonate, which is limited to the polycarbonate and has problems of poor compatibility, etc.
Therefore, the invention develops a polycarbonate with high fluidity and high chemical resistance by introducing new monomers from a coalescence structure and controlling the ratio of the monomers and utilizing a melt transesterification process, and can be applied to the fields with both fluidity and chemical resistance.
Disclosure of Invention
In order to overcome the defects of the prior art, the polycarbonate with high heat resistance and high chemical resistance, the preparation method and the application thereof are provided.
In one aspect, the present invention provides a copolycarbonate comprising the structure:
