FLAME RETARDANCY OF STEREOCOMPLEXED POLYLACTIDE: PROCESSING, CHARACTERIZATION AND REACTION TO FIRE

摘要

Polylactide (PLA) is synthesized from renewable resources and currently deserves a particular attention in the area of environmentally degradable polymer materials [1]. PLA has good mechanical properties, thermal plasticity and biocompatibility and it is thus a promising polymer for various end-use applications (mainly packaging and fibers). Manufacturers expect some durable applications for PLA with targeted applications including E&E, transportation, etc... Nevertheless, the major part of these applications requires improvements of the properties of the PLA, like crystallinity, enhanced thermal properties (melting temperature ...) ... which cannot be reached by PLA. It can be achieved by the stereocomplexation of L-lactide and D-lactide to make thermally improved polylactides [2]. These materials exhibit higher transition temperature, higher crystallinity rate and higher melting point.
