In other words, the reactive water is constant and independent of
total water content of the polymer. The analogous conclusion can
In our study, the
extra water of PLA/NR blends than neat PLA is contained in the
dispersed NR particles and it does not affect the content of the
reactive water. So, the hydrolysis rate do not affect by NR. This
further confirms that the introduction of NR has no effect on the
hydrolysis of PLA, which is very useful for keeping the biodegradability
of PLA when toughened by NR and hence for applying the
PLA/NR materials.
