Abstract

ionedbrytbare blandinger av L-laktid, D-laktid, meso D,L-laktid og rasemisk D,L-laktid egnet for bøyelige filmer og andre emballasjeformål fremstilles ved polymerisering av L-laktid, D-laktid, D,L-laktid eller blandinger derav under anvendelse av en katalysator ved kontrollerte betingelser slik at polymeren i blandingen kan bli plastisert ved hjelp, av ureagert laktidmonomer. Miljømessig bionedbrytbar polymer, blandinger og fremgangsmåte for en polymer og en blanding. Den bionedbrytbare polymer omfatter polymeriserte melkesyre-enheter med struktur (I), hvori n er et helt tall mellom 75 og 10.000 og alfakarbonatomet er en blanding av L- og D-konfigurasjoner, hvor den uorienterte polymer har en strekk-styrke på minst 350 kg/cmog en tangentmodul på minst 14.000 kg/cm. En ytterligere utførelsesform tilveiebringer en miljømessig nedbrytbar blanding omfattende blandinger av en fysikalsk blanding av polymelkesyre og en polymer valgt fra gruppen bestående av polymerer av etylentereftalat, en polymer eller kopolymer av styren, etylen, propylen, vinylklorid, vinylacetat, alkylmetakrylat, alkylakrylat og fysikalske blandinger derav.
