The invention relates to an azonium-ionized poly(styrene-b-isobutylene-b-styrene) triblock copolymer and a preparation method thereof. According to the invention, poly(styrene-b-isobutylene-b-styrene) is adopted as a substrate material, and is sequentially processed through chloromethylation and azonium ionization, such that the azonium-ionized poly(styrene-b-isobutylene-b-styrene) triblock copolymer is obtained. The azonium ionic salt-containing substituted poly(styrene-b-isobutylene-b-styrene) triblock copolymer prepared with the method provided by the invention has the advantages of high ion content, high ionization degree and high ionization reaction efficiency. The preparation method is simple.
Description
Technical field: [0001] The invention relates to the field of azonium ionized polymers and a preparation method thereof, in particular to azonium ionized poly(styrene-b-isobutylene-b-styrene) triblock copolymers and a preparation method thereof. Background technique: [0002] Thermoplastic elastomers have the elastic deformation ability similar to rubber at room temperature, and have the processing properties of thermoplastics when heated to a certain temperature. Poly(styrene-b-isobutylene-b-styrene) triblock copolymer (abbreviation: SIBS) is a kind of soft segment fully saturated thermoplastic elastomer, and the chemical structure of polyisobutylene segment in the middle endows poly(styrene-b - Isobutylene-b-styrene) triblock copolymers have excellent thermo-oxidative stability, aging resistance, barrier properties, processability and reprocessability, shock absorption properties and barrier properties to water and air. In addition, poly(styrene-b-isobutylene-b-styrene) t...
