Abstract

Hydroksykarboksylsyrekopolyester av R-stereospesifikk konfigurasjon inneholder en hoveddel av første gjentagende enheter som har evne til å danne en meget krystallinsk hiayt-smeltende homopolyester og en mindre del av andre gjentagende enheter som har evne til når de tilfeldig kopolykondenseres med de første gjentagende enhetene å senke smeltepunktet av homopolyesteren og er kjermetegnet ved et eller fiere trekk; høyere krystallinsk smeltepunkt, kortere krystallinsk tid, høyere risstøtstyrke ved alder 1 måned, sammenlignet med tilsvarende tilfeldig polyester, og hoveddelen av gjentagende enheter i polyesterkjeden er tilstede i blokkene lenger enn det som tilsvarer den samlede molare proporsjonalitet, Kopolyesteren kan bli laget ved fermentering, regulering av fordeling av gjentagende enheter med referanse til tilførselsmønstersubstrater som tilsvarer de respektive gjentagende enheter.
