Processing Stabilization of Polyolefin Recyclates Using Alditols in Combination With α‐Tocopherol: A Sustainable Alternative to Phosphites

Journal of Vinyl and Additive Technology, EarlyView.
A novel bio‐based stabilizer system significantly improves the quality of polyolefin recyclates during multiple recycling cycles. ABSTRACT This study introduces a novel bio‐based stabilizer system for polyolefin recyclates that combines alditols with small amounts of α‐tocopherol as a sustainable alternative to conventional phosphite additives. The aim

A N,N′‐p‐Tolyl Substituted Diazadiene Ligand with a Dithienylethane Backbone in Hexacoordinated Group IV Tetrachlorido Complexes—Steric Repulsions Govern the Axial Chirality Mode

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The chelating imino groups in [MCl4(DADDTEthane)] (M = Ti, Zr, Hf) give rise to a planar five‐membered (‐N=C‐C=N‐)M metallacycle. The two thiophene rings of the ligand backbone reside in a noncoplanar arrangement concerning the metallacycle, giving rise to two chiral C–C axes in the ligand backbone.

Optimised Molecular Traps and Conjugated Structures for Superior High‐Temperature Capacitive Performance in Polyimide

High Voltage, EarlyView.
ABSTRACT In the fields of automotive electronics, power electronics, and aerospace, environmental conditions are often extremely harsh, particularly for materials that must endure high temperatures, high power and require high stability. The degradation of capacitance performance in polymer dielectrics under high electric fields and elevated ...

Compatibility of personal care thickening polymers in sulphate‐free surfactants

International Journal of Cosmetic Science, EarlyView.
Phase behaviour for alpha olefin sulfonate surfactant 10–15 wt% combined with 1 wt% sodium carboxy methyl cellulose, clearly indicating the sensitivity in miscibility when adding various levels of background salt. Abstract Objective Formulators today know that when traditional surfactants and polymers are replaced new problems occur. What was before a ‘
