Bio-polyols were prepared by the following methods: transesterification, transamidization and two-steps method of epoxidation and oxirane rings opening.}, doi = {10.4467/2353737XCT.14.351.3662}, url = {https://ejournals.eu/czasopismo/czasopismo-techniczne/artykul/environmentally-friendly-polyurethane-polyisocyanurate-foams-for-applications-in-the-construction-industry} }
