The stress/strain plots (Figure 5) show that the
composites have reduced elongation, increased modulus
while the PLA-g-MA compatibilized composites have better
tensile strength. In contrast Plackett[19] observed reduced
tensile strength in of jute/PLA composites compatibilized
with PLA-g-MA that was prepared via solution polymerization
and attributed this to the low Mw of the maleated PLA,
which was around 28 000.
