Abstract

The invention relates to a polyphenylene sulfide amide polymer as well as preparation and application thereof, and belongs to the field of polymer synthesis and processing. The invention provides a polyphenylene sulfide amide polymer. The structural formula of the polymer is shown as a formula I or a formula II. The polyphenylene sulfide amide prepared by the invention has novel functions of high temperature resistance, high mechanics, dissolvability, solvent resistance, high light transmittance or high refractive index and the like. Compounding the obtained polymer with a calcium salt compound to prepare a composite material; compared with orthopedic medical equipment products such as PA66 and PA6, the obtained polyphenylene sulfide amide calcium salt composite material has more stable processing size stability and can be used as a potential precise bone support material.

Description

technical field [0001] The invention relates to a type of polyphenylene sulfide amide polymer and its preparation and application, and belongs to the field of polymer synthesis and processing. Background technique [0002] Polyphenylene sulfide (PPS) is a highly crystalline polymer, which is the most widely used variety in engineering plastics at present. Due to its excellent chemical corrosion resistance, high temperature resistance, low density and hydrolysis resistance, it is widely used in It has a wide range of applications in the chemical industry, machinery manufacturing, aerospace, electronic vehicles and other fields. Regarding the synthesis of PPS, there have been a large number of literature reports at this stage. For example, CN1143652A reported that in polar solvents, sulfur was used as the sulfur source, and linear PPS resin was prepared under pressure in the presence of a reducing agent; CN1793202A reported that sodium sulfide, dichloride Benzene is used as r...
