[HTML][HTML] Bringing non-isocyanate polyurethanes closer to industrial implementation using carbonated soybean oil-based amino hardeners
A Centeno-Pedrazo, Z Freixa, R Feola, F Lunzer… - Progress in Organic …, 2023 - Elsevier
The polyaddition between cyclic carbonates and diamines to form non-isocyanate
polyurethanes (NIPUs) is a safer alternative than traditional PU synthesis. However, the
lower reactivity of cyclic carbonates requires of long reaction times and/or high temperatures
for their curing, hampering their industrial implementation in the coating industry. Starting
from carbonated soybean oil (CSBO) and amine excess, and through a stepwise addition
process, cyclic carbonate full conversion has been achieved, yielding amino-terminal NIPUs …
