Resumo(s)
The development of polyols by the oxypropylation of
abundant and renewable vegetable and animal resources
constitutes an original approach to the exploitation of the
biomass. Cellulose, starch, chitosan, chitin, different types
of lignins, cork and more complex structures like sugar
beet pulp, are among the documented examples. All these
systems displayed a similar pattern in terms of the grafting
of short poly(propylene oxide) (POP) chains from the OH
groups of the substrate, albeit of course each situation
required a specific set of optimized experimental
conditions to transform the natural solid into a viscous
polyol. The transformation of these polyols into
polyurethanes is the only operation which has been studied
to date as a form of their exploitation into polymer
materials. In this work, the more promissing
were selected for chemical modifications involving first
ester and urethane formations with aliphatic and aromatic
monofunctional reagents.
