Abstract

AbstractEnantiomeric star-shape block copolymers of ε-caprolactone and lactide with different molar masses and compositions were synthesized using pentaerythritol/tin(II) 2-ethylhexanoate as initiating system. Stereocomplex formation between pair of enantiomeric blocks of star arms was investigated. Thermal properties of both copolymers and obtained stereocomplexes were examined. A rise of above 50 °C of melting temperature of polylactide phase was observed as a consequence of stereocomplex creation.
