However, surprisingly, after
annealing the impact strength of the PLA/EGMA blends increased
drastically: the value for the annealed L80-200 was 72 kJ/m2
, ca. 50
times higher than that for the neat as-prepared PLA-L. As-prepared
acrylonitrile–butadiene–styrene (ABS) sample measured under the
same experimental conditions showed an impact strength as high
as 21 kJ/m2
, however, the present PLA/EGMA far exceeded this
strength so that the specimen was unseparable even after hit at
high energies of 4 J
