solubility parameters have been used for decades to determine polymer
solubility. In most cases, these parameters, based on the various
solvent-polymer attraction forces, do provide for prediction of polymer
solubility in a given solvent. However, there are instances where the polymers
do not interact with solvents in a way predicted by these parameters and
understanding the cause of these differences requires more fundamental
research. Recently, researchers at The National Center for Scientific Research
(France) Used PolySciTech (www.polyscitech.com) poly(lactides) of two different
molecular weights (PolyVivo AP086 and AP114) along with PMMA and PS and a wide
variety of solvents to perform an in-depth study on solvent-polymer interaction
looking at both solubility and swelling. This research holds promise for a more
fundamental understanding of polymers and solvents which can be applied to a
wide range of applications both medical and industrial. Read more: Vayer,
