Abstract

Abstract: A preparation method of isocyanate-free polyurethane was proposed using dimethylhexane-1,6-dicarbamate (HDU) as a curing agent. The structure of the obtained polyurethane was confirmed by means of IR, NMR, and GPC. When the molar ratio of HDU to polyether glycol 3000 was 1:1, the reaction temperature was 180 ℃, a weight-average molecular weight of 8.5×104 was obtained after 1 hour.

Key words: non-isocyanate polyurethane, dimethylhexane-1, 6-dicarbamate, polyether glycol, polyethlene glycol, synthesis, characterization
