Polylactic Acid for Surgical Implants
Archives of Surgery, 1966LACTIC acid in its racemic or optically active form can undergo acid catalyzed homopolymerization to yield a polymer of lower molecular weight, which is not suitable for plastic or fibers.1However, the cyclic diester, the lactide2of lactic acid, can polymerize by anionic ring opening addition mechanism under the influence of catalysts to a high polymer,

Polylactic acid (PLA), a bio-based polymer produced from fermentation of starch into lactic acid followed by polymerization process, is considered to be a sustainable packaging material. Stereochemical isomers, P-LLA and P-DLA, affect polymer final properties and can be used in controlled release packaging (CRP) to provide a wide range of release ...

Biodegradable polylactic acid (PLA)
Physical Sciences Reviews, 2021Abstract Polylactic acid (PLA) is a biodegradable material that can be processed using the common processing techniques, such as injection molding, extrusion, and blow molding. PLA has widely been researched and tested due to its biodegradable nature. As a biodegradable material, PLA can be subject to some inherently poor qualities, such

Polylactic acid is proving to be a viable alternative to petrochemical-based plastics for many applications. It is produced from renewable resources and is biodegradable, decomposing to give H2O, CO2, and humus, the black material in soil. In addition, it has unique physical properties that make it useful in diverse applications including paper coating,

Polylactic acid (PLA) is a biodegradable polymer with exceptional properties that has been studied extensively for the past 25 years. The possibility of using devices in human body with minimum inflammation and infection to allow natural healing has obliged researchers to search for biocompatible and biodegradable alternatives.

Enzymatic Hydrolysis of Polylactic Acid Fiber
Applied Biochemistry and Biotechnology, 2010This study investigated the optimization of the enzymatic processing conditions for polylactic acid (PLA) fibers using enzymes consisting of lipases originating from different sources. The hydrolytic activity was evaluated taking into consideration the pH, temperature, enzyme concentration, and treatment time.
