Successive Mechanical Recycling of Poly(lactic Acid) by Injection Molding: Evolution of Molecular, Thermal, and Mechanical Properties

Macromolecular Materials and Engineering, EarlyView.
This study investigated how successive injection molding recycling affects the properties of poly(lactic acid) (PLA). Gel permeation chromatography showed a two‐thirds molar mass reduction after ten reprocessing cycles. Differential scanning calorimetry revealed lower glass transition and cold crystallization temperatures.

Mechanical Reinforcement of Polymer Nanocomposites with Different Network Structure of Polymer Grafted Nanoparticles

Macromolecular Materials and Engineering, EarlyView.
Due to the different conformation structures of the grafting chains on the surface of silica, the nanoparticles contact each other by brush chains and bridge into a polymer‐mediated nanoparticle network in HDPE14K/HDPE1K‐g‐SiO2 PNCs, resulting in a more significant modulus reinforcement than that of PP370K/PP90K‐g‐SiO2 PNCs with a soft interfacial ...

Bio‐Based Epoxy Resins from Estragole: Achieving High Glass Transition Temperatures Comparable to DGEBA and Simultaneously Low Viscosities

Macromolecular Materials and Engineering, EarlyView.
Two novel bio‐based epoxy monomers, diglycidyl‐4‐allylphenol (DG‐4A) and triglycidyl‐diallylphenol (TG‐DA), derived from estragole (92% and 72% bio‐content), were synthesized and cured with isophorone diamin (IPDA) and 4,4´‐diaminodiphenyl sulfone (DDS). The resins show high Tgs, with DG‐4A reaching and TG‐DA exceeding DGEBA‐based systems. These resins
