Recently, it has been shown by our group that the composition dependence of the glass transition temperature (T,) of polymer-diluent (and polymer-polymer) systems has to be described, in some occasions, by two different analytical expressions, one applicable above and one below a critical temperatur
## Abstract The effects of dissolved carbon dioxide (CO~2~) molecules on the glassβtransition temperature as well as the crystallization kinetics of poly(lactic acid) have been investigated with a novel device that combines ultrasonic and volumetric measurements. Ultrasonic parameters such as the s
