Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania bezizocyjanianowych poliuretanów metodą poliaddycji pięcioczłonowych bis(cyklicznych węglanów) otrzymanych z polieterodioli pochodzących z surowców roślinnych, charakteryzujący się tym, że stosuje się bis(cykliczny węglan) otrzymany z poli(glikolu trimetylenowego) pochodzenia roślinnego o średniej masie molowej od 250 do 2700 g/mol oraz bio-epichlorohydryny otrzymywanej z odpadowej gliceryny zaś bis-cykliczny węglan poddaje się reakcji z diaminami lub/i poliaminami z tym, że w pierwszym etapie poli(glikol trimetylenowy) poddaje się reakcji z bio-epichlorohydryną otrzymując eter diglicydylowy, zaś w drugim etapie w temperaturze od 100 do 125°C eter diglicydylowy poddaje się reakcji z CO<sub>2</sub> otrzymując bis(cykliczny węglan), a następnie w trzecim etapie bis(cykliczny węglan) poddaje się reakcji addycji z di- lub poliaminami w temperaturze od 60 do 120°C w atmosferze powietrza lub gazu obojętnego. Przedmiotem zgłoszenia sa też bezizocyjanianowe poliuretany otrzymywane tym sposobem.The subject of the application is a method of obtaining nonisocyanate-free polyurethanes by polyaddition of five-membered bis (cyclic carbonates) obtained from polyether diols derived from plant materials, characterized by the use of bis (cyclic carbonate) obtained from poly (trimethylene glycol) of vegetable origin with an average molecular weight from 250 up to 2700 g / mol and bio-epichlorohydrin obtained from waste glycerin, while the bis-cyclic carbonate is reacted with diamines and / or polyamines, but in the first stage poly (trimethylene glycol) is reacted with bio-epichlorohydrin to obtain diglycidyl ether, and in the second step, at a temperature of 100 to 125 ° C, the diglycidyl ether is reacted with CO <sub> 2 </sub> to give bis (cyclic carbonate), and then in the third step, bis (cyclic carbonate) is subjected to an addition reaction with di - or polyamines at a temperature of 60 to 120 ° C in an atmosphere of air or an inert gas. The subject of the application are also non-isocyanate-free polyurethanes obtained in this way.
