POLYVINYL THIOETHER ESTER, PREPARATION METHOD THEREFOR AND USE THEREOF

WIPO Patent Application WO/2021/031818

A1

Disclosed are a polyvinyl thioether ester, a preparation method therefor and the use thereof. The polyvinyl thioether ester is obtained by subjecting a binary acetylenic acid ester-based internal-alkyne monomer and a binary mercapto monomer as raw materials to a solution polymerization reaction. The reaction raw materials of the polymerization reaction are easy to obtain, and no by-products are produced during the process of the polymerization reaction. The polymerization reaction has a wide substrate applicability and a good functional group compatibility, such that various functional groups can be conveniently introduced. No catalyst is used in the polymerization reaction, and as such, the influence of a catalyst residue on the optical and electrical properties and the biological properties of a polymer material can be eliminated. The prepared polyvinyl thioether ester has a good workability, a higher heat stability and aggregation-induced luminescence performance, and has application value in terms of optical plastics, biomedical materials, fluorescent sensing, etc.
