Small amounts of poly(d-lactic acid) on the properties of poly(l-lactic acid)/microcrystalline cellulose/ poly(d-lactic acid) blends

Results in Materials, 2020
Stereocomplexation is utilized to improve and control the mechanical and thermal properties of poly(lactic acid) (PLA) where enantiomeric polymers poly(l-lactic acid) (PLLA) and poly(d-lactic acid) (PDLA) form stereocomplexation.

Abscess formation caused by a foreign body reaction to a poly-d, l-lactic acid (PDLLA) absorbable plate for zygomaticomaxillary complex (ZMC) fracture

Bulletin of the National Research Centre, 2022
Background The poly-d, l-lactic acid absorbable plate does not contain poly l-lactic acid, which is the main factor in foreign body reactions; therefore, with use of this plate, a foreign body reaction is unlikely.
