We prepared and studied a series of triblock copolymers based on poly(ethylene glycol) (PEG) poly(lactic acid) (PLA). PLA blocks were in situ by ring-opening polymerization (ROP) lactide (LA) onto the two sites PEG. While our recent work similar with varying LA/PEG molar ratios fixed PEG [Bikiaris, N. D. Mater. Today Commun. 2024, 38, 107799], herein, we kept this ratio quite low, at 640/1, employed different molecular weights, Mn, initial 1, 4, 6, 8 kg/mol. The triblocks demonstrated high homogeneity, as manifested single thermal transition (glass transition, crystallization) corresponding alternations systematic way Mn With increase latter accelerated segmental mobility lowering Tg up to 15 K recorded, accompanied suppression chain fragility (cooperativity). Compared linear PLAs various Mns [Klonos, P. A. Polymer 305, 127177] other PLA-based ROPs, overall copolymers, here sees play role plasticizer PLA, leading increased free volume. Due these effects, general, low crystalline fraction (∼3%) was significantly enhanced (20–26%), formed spherulites mainly enlarged. Contrary these, nucleation barely affected; thus, exhibited altered semicrystalline morphologies compared that neat PLA. Both aspects dynamics, volume crystallization, connected processability well performance systems, considering envisaged biomedical applications.

Abstract Polylactic acid (PLA) is a promising biodegradable material for packaging, but its limited ductility restricts use. Blending PLA with flexible polyesters can improve often reduces transparency. To address this, two plasticizers derived from the natural phenolic compound cardanol (CD)—cardanol acetate (CA) and epoxidized (ECA)—were synthesized to enhance PLA's without compromising films were plasticized varying concentrations of CA ECA using melt mixing‐extrusion. The results showed that significantly improved flexibility compatibility due interactions between epoxy groups carboxyl end groups. PLA‐15ECA exhibited tensile strength 41.9 MPa remarkable elongation at break 336.6%, compared pure 52.1 13.7%, respectively. Transparency was maintained (transmittance >85%), thermal stability excellent, only 2% mass loss after 2 h 200°C. This study highlights potential performance eco‐friendly packaging applications. Highlights Synthesize cardanol‐based Plasticizer active‐group reactivity solubility are key modification. has an 336.6%. ‐ balance strength, toughness, keep
