Resumen:
In this study, rigid thermoset polymers were
prepared from radical copolymerization of linseed oil monoglyceride
maleates with styrene (St). First, linseed oil monoglycerides
(LOMGs) were obtained from the reaction of
linseed oil with glycerol at 220240°C. Then, LOMGs were
reacted with maleic anhydride at 80°C to produce the
LOMG maleate half esters. The reactions were followed by
FTIR spectroscopy and size exclusion chromatography
(SEC) and the final resin was characterized by 1H-NMR
spectroscopy. Finally, radical copolymerization of the
LOMG maleates with 20, 40, 60, and 80% by weight of St was
performed to produce rigid, thermoset polymers. The thermomechanical
properties and fracture behavior of the cured
copolymers, as a function of the percentage of St, were
measured and analyzed. The copolymer with 40% by weight
of St was the material with better mechanical and fracture
behavior.
