Patent ID: 11787907

Abstract:
Disclosed are a polyvinyl thioether ester, a preparation method therefor and use thereof. The polyvinyl thioether ester is obtained by subjecting a binary acetylenic acid ester-based internal-alkyne monomer and a dithiol monomer as starting materials to a solution polymerization reaction. The staring 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, 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.
