The DSC study of PLA and natural rubber blends by Jaratrotkamjorn
also observed similar thermal behavior of the
blends and little change in Tg. The value of Tg in their report was
about 58 ± 2 C, which is approximately 5 C lower than ours. The
glass transition temperature compares well with Tg = 61.8 C as reported
by Cao
