Rheological Properties of Poly lactic Acid

Rotational and capillary rheometers are devices that can be employed to gain data on the shear viseosity of polymers. Rotational rheometers are primarily used for low-shear-rate

Blends of poly(lactic acid) and poly(butylene-adipate-co-terephthalate) were prepared in the presence of varying concentrations of LlOl RI by ColteUi et al. (2010). The blends were characterized by morphology, rheology, and mechanical properties. 

Dogan et al. (2013) prepared blends of poly(lactic acid) with TPU through addition of 1,4-phenylene diisocyanate coupling agent. Characterization techniques included mechanical, thermal, morphological, and rheological properties.
