The polymerization involves the opening of the epoxy ring to deliver the linear polyethers bearing free tetrahydroindole rings and oxyethylene or vinyloxy groups in the side chain. The polyethers are soluble in ethanol, benzene, chloroform, dioxane, DMF, and DMSO. The polyethers obtained exhibit the properties of high-resistance organic semiconductors: their electrical conductivity reaches 10\u221214 S\/cm.<\/jats:p>","DOI":"10.3390\/polym14204467","type":"journal-article","created":{"date-parts":[[2022,10,24]],"date-time":"2022-10-24T08:19:06Z","timestamp":1666599546000},"page":"4467","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Synthesis of Functional Polyesters N-(2,3-epoxypropyl)-4,5,6,7-tetrahydroindole by Anionic Ring-Opening Polymerization"],"prefix":"10.3390","volume":"14","author":[{"given":"Marina","family":"Markova","sequence":"first","affiliation":[{"name":"A.E.
