PLA ndechimwe chezvakanyanya kuparara zvigadzirwa zvepurasitiki. Polylactic asidhi ipolymer yakagadziriswa kubva kulactic acid seyakanyanya mbishi zvinhu. Parizvino, ndiyo yakakura kwazvo, yakakura uye inonyanya kushandiswa biodegradable plastiki pasi rose.
Pane nzira mbiri dzekugadzira PLA, dzinoti lactide ring-open polymerization uye yakananga polycondensation, iyo lactide ring-yakavhurika polymerization inoshandiswa zvakanyanya. Mune lactide mhete-inovhura polymerization, iyo synthesis uye kucheneswa kwepakati lactide ndiyo yakakosha tekinoroji uye kuoma mukuita. Mamiriro ekuita akaomarara, maitiro akaomarara, zvinodiwa zvehunyanzvi zvakakwira, uye mutengo wekugadzira wakakwira.
