Abstract

Environmental concerns have led to the development of biorenewable polymers with the ambition to utilize them at an industrial scale. Poly(lactic acid) and poly(hydroxyalkanoates) are semicrystalline, biorenewable polymers that have been identified as the most promising alternatives to conventional plastics. However, both are inherently susceptible to brittleness and degradation during thermal processing; we discuss several approaches to overcome these problems to create a balance between durability and biodegradability. For example, copolymers and blends can increase ductility and the thermal-processing window. Furthermore, chain modifications (e.g., branching/crosslinking), processing techniques (fiber drawing/annealing), or additives (plasticizers/nucleating agents) can improve mechanical properties and prevent thermal degradation during processing. Finally, we examine the impacts of morphology on end-of-life degradation to complete the picture for the most common renewable polymers.

  • Degradable analogues composed of poly(lactide) as hard A blocks and an amorphous aliphatic polyester homopolymer or statistical copolymer as the soft B block have been investigated.

    “Inspired by the incredible versatility of styrenic ABA triblock polymers, we and others have investigated degradable analogues composed of poly(lactide) (PLA) as the hard ' A ' blocks and an amorphous aliphatic polyester homopolymer 7 -17 or statistical copolymer 18,19 as the soft ' B ' block.”

  • The majority of aliphatic lactones that have been polymerized are derived from fossil fuels or from prohibitively expensive natural products.

    “Although myriad aliphatic lactones with diverse structures have been polymerized, the majority of these monomers have been derived from fossil fuels or from prohibitively expensive natural products.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
