Long Versus Short Chain Covalent Functionalization in the Preparation of Mechanochromic Polymers

open access: yesChemistry–Methods, Volume 6, Issue 5, May 2026.
A perylene bisimide (PBI) macromechanophore featuring poly(ε‐caprolactone) (PCL) spacers was covalently incorporated into poly(styrene‐ethylene‐butylene‐styrene) (SEBS) and low‐density polyethylene (LLDPE) matrices. Compared to a short‐spacer PBI, the long‐spacer enhanced force transduction while preserving mechanical properties.

Phthalates and Mixed Alkyl Phthalates Analysis in Plastics Using GC‐MS With Cold EI

open access: yesJournal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Phthalates are esters of phthalic acid. They are widely used as plasticizers to improve the flexibility, durability, and performance of plastics in a variety of products. However, certain phthalates are associated with significant health risks, including endocrine disruption and reproductive toxicity.
