Linear phosphorus-containing (co)polyesters are described, including their synthesis, thermal analysis, conductivity, and non-flammability. Polycondensation of phenylphosphonic dichloride (PPD) with poly(ethylene glycol) (PEG 12000) with and without bisphenol A (BA) was carried out using solid-liquid phase transfer catalysis. Potassium phosphate is used as base. Yields in the range of 85.0\u201388.0%, and inherent viscosities in the range of 0.32\u20130.58 dL\/g were obtained. The polymers were characterized by gel permeation chromatography, FT-IR, 1H- and 31P-NMR spectroscopy and thermal analysis. Their flammability was investigated by measuring limiting oxygen index values. The polymers are flame retardants and begin to lose weight in the 190 \u00b0C\u2013231 \u00b0C range. Solid phosphorus- containing (co)polyesters were complexed with lithium triflate and the resulting ionic conductivity was determined. Conductivities in the range of 10\u22127\u201310\u22128 S cm\u22121 were obtained.<\/jats:p>","DOI":"10.3390\/molecules17089090","type":"journal-article","created":{"date-parts":[[2012,7,31]],"date-time":"2012-07-31T10:44:19Z","timestamp":1343731459000},"page":"9090-9103","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Synthesis of New Phosphorus-Containing (Co)Polyesters Using Solid-Liquid Phase Transfer Catalysis and Product Characterization"],"prefix":"10.3390","volume":"17","author":[{"given":"Smaranda","family":"Iliescu","sequence":"first","affiliation":[{"name":"Institute of Chemistry, Romanian Academy, 24 Mihai Viteazul Bvd., Timisoara 300-223, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maite-Gyl","family":"Augusti","sequence":"additional","affiliation":[{"name":"Instituto Tecnol\u00f3gico de la Energ\u00eda, Av.
