Polyaddition using isocyanate and polyol forms polyurethane elastomer (PUE). However, this method
has rarely been applied to the construction of PUEs containing sucrose. Hence, the introduction
of sucrose (disaccharide) as a cross-linker via polyaddition remains a challenging subject in
polymer chemistry. Here, we report the synthesis of PUEs using an aromatic isocyanate (4,4’-diphenylmethane
diisocyanate), polyols including a polyether polyol (polytetramethylene glycol)
and two polyester polyols (polycaprolactone and polycarbonate diols), and sucrose as a crosslinker
by a one-shot method. The PUEs containing sucrose were successfully produced. The use of
sucrose was essential to obtain the desired PUEs containing sucrose units in the main chain.
