In order to reduce the production cost of polylactic acid (PLA), l -lactic acid was polymerized by direct polycondensation (DP) under vacuum without catalysts, solvents and initiators. Experiments were conducted at polymerization temperatures ( T p )

The hydrophobic sorption distillation (HSD) model is proposed to explain the mechanism of pervaporation (PV) of ethanol solution by hydrophobic porous membranes. We tested new PTFE and PP membranes and the results have been compared to previously pub
