Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania polioli, który prowadzi się tak, że do reaktora wprowadza się poli(alkohol winylowy), glicydol w ilości od 5 do 7 moli na 1 mol merów poli(alkoholu winylowego) oraz od 11 do 14 moli węglanu etylenu na 1 mol merów poli(alkoholu winylowego). Zawartość reaktora ogrzewa się do temperatury z zakresu od 120°C do 140°C i jednocześnie miesza się z prędkością od 500 do 2000 obrotów na minutę. Ogrzewanie prowadzi się do momentu całkowitego rozpuszczenia poli(alkoholu winylowego), po czym temperaturę reakcji podnosi się co najwyżej do 190°C i reakcję prowadzi się do zakończenia reakcji poli(alkoholu winylowego) z glicydolem. Następnie mieszaninę reakcyjną oziębia się do temperatury co najwyżej 80°C i dodaje się do niej węglan potasu w ilości od 0,6% do 2,2% mas. w stosunku do masy pozostałych składników. Zawartość reaktora ogrzewa się do temperatury z zakresu od 160°C do 190°C i miesza się go z prędkością od 400 do 600 obrotów na minutę do czasu zakończenia reakcji.
