Resumen:
The objective
of this work is to produce new materials based on renewable sources that exhibit
good mechanical properties and biodegradability characteristics. The flexible polyurethane
foams from castor oil modified with maleic anhydride (MACO) were synthesized. The
synthesis involved a single-stage process by mixing castor oil/MACO
(weight ratios 75:25 and 25:75) and 2-4 toluene diisocyanate (TDI) in stoichiometric
amount of OH:NCO. Their final properties were evaluated and compared
with traditional polyurethane foam based on polyether.
