However, the cold crystallization of PLA is reduced with increasing NR content.
No obvious changes are observed in the glass transition temperature (Tg) of PLA (around 60C) in various blends, which confirms their immiscible behavior.
The crystallization behavior of a crystallisable matrix in immiscible blends can be affected by two major factors, the impurities induced during meltmixing and the nucleating activity of the interface [33].
