Recent complications on the use of polypropylene meshes for hernia repair has led to the development of meshes or films, which were based on resorbable polymers such as polycaprolactone (PCL), polylactic acid (PLA) and poly(lactic-co-glycolic acid) (PLGA).

Poly(lactic acid) crystallization
Progress in Polymer Science, 2012Abstract Poly(lactic acid) is a biobased and compostable thermoplastic polyester that has rapidly evolved into a competitive commodity material over the last decade. One key bottleneck in extending the use of PLA is the control of its crystallinity. Understanding the crystallization behavior is particularly crucial to control PLA's degradation rate ...

Poly(lactic acid) modifications
Progress in Polymer Science, 2010Abstract Poly(lactic acid) or polylactide (PLA) is the most extensively researched and utilized biodegradable and renewable thermoplastic polyester, with potential to replace conventional petrochemical-based polymers. In recent times, several PLA-based technologies have emerged with an emphasis on achieving chemical, mechanical, and biological ...

Abstract Poly (lactic acid) or polylactide (PLA) is an aliphatic thermoplastic polyester produced from renewable resources and is compostable in the environment. Because of the massive use of foamed products of petroleum-based polymers, PLA foams have been considered as substitutes for some of these products.

Abstract Poly(lactic acid) (PLA) depolymerases are categorized into protease-type and lipase-type. Protease-types can hydrolyze poly( l -lactic acid) (PLLA) but not poly( d -lactic acid) (PDLA). Lipase-types, including cutinase-like enzyme (CLE) from Cryptococcus sp. strain S-2 preferentially hydrolyze PDLA.

AbstractStereoblock poly(lactic acid) (sb‐PLA) is incorporated into a 1:1 polymer blend system of poly(L‐lactic acid) (PLLA) and poly(D‐lactic acid) (PDLA) that has a high molecular weight to study its addition effect on the stereocomplex (sc) formation of PLLA and PDLA. The ternary polymer blend films are first prepared by casting polymer solutions of

AbstractA novel PLA‐based polymer containing reactive pendent ketone or hydroxyl groups was synthesized by the copolymerization of L‐lactide with ε‐caprolactone‐based monomers. The polymer was activated with NPC, resulting in an amine‐reactive polymer which was then cast into thin polymeric films, either alone or as part of a blend with PLGA, before ...
