ʻO ka D-(+)-lactide kahi diester cyclic o ka waikawa lactic, kahi huahana i hana ʻia e nā hunaola ʻiʻo a me nā hunaola koko ʻulaʻula i ka wā e wāwahi ai ke kino i nā kalapona no ka ikehu ma nā pae oxygen haʻahaʻa.
ʻO ke kikoʻī o D(+)-LACTIDE Hiki ke polymerized ʻia ka Lactide i ka waikawa polylactic me ka hoʻohana ʻana i nā catalysts kūpono, e hopena ana i nā mea me nā waiwai pono.
