There is a sharp drop in storage modulus observed at around −48 C related to the glass transition of POM. The incorporation of PLA into POM leads to a decline in storage modulus due to the presence of a soft PLA domain in the POM matrix, and such a decline seems to be more notable with an increase of PLA content.
