“…The melt process is carried out by heating the material above its melting temperature to get the desired product [ 30 ] and also is necessary take into account during the blending process, the shearing conditions [ 7 ]. At lower processing speeds between 20 and 80 rpm, various blending systems were obtained from mixers or torque rheometers [ 8 , 9 , 13 , 24 , 25 , 26 , 31 ], or from twin screw extruders [ 14 , 16 , 20 ], using plasticizers such as ATBC, PEG or TBC, and PLA or a PLA-blend, varying only the plasticizer content in the final PLA-based blend; generally, for processing speeds above 100 rpm, twin screw extruders [ 1 , 2 , 6 , 7 , 10 , 15 , 22 , 23 ] are used to obtain the plasticized PLA-based blend material from ATBC, OLA, oligoesteres or malonate oligomers to plasticize the PLA or a PLA-blend. In the most of cases, especially with ATBC, the plasticizer decreases the glass transition temperatures and improve the ductile properties but there is always a migration of the plasticizer from the PLA matrix.…”
