Telomerization of Isoprene with Short Alcohols Using Novel Solid Molecular Phosphine Polymers

ChemCatChem, Volume 18, Issue 8, 28 April 2026.
Solid molecular catalysts based on triphenylphosphine and tris(o‐methoxyphenyl)phosphine were designed and loaded with palladium via pre‐loading or in‐situ‐loading for use in telomerization with short alcohols. The pre‐loaded catalyst proved to be significantly more active.

Synthesis of Monodisperse Low‐Crosslinked Polymer Microspheres With Sulfonic Acid by Precipitation Polymerization

Journal of Polymer Science, Volume 64, Issue 7, Page 1553-1567, 1 April 2026.
An efficient strategy for preparing monodisperse crosslinked polymer microspheres with phenylsulfonate via precipitation polymerization has been successfully established. Monodisperse microspheres are successfully obtained using a designed crosslinker even when the total crosslinker content was below 20 mol%. All the polymer microspheres possess a well‐

Analysis of Insect Cuticular Compounds by Non-lethal Solid Phase Micro Extraction with Styrene-Divinylbenzene Copolymers

, 2012
Insect cuticular hydrocarbons including relatively non-volatile chemicals play important roles in cuticle protection and chemical communication. The conventional procedures for extracting cuticular compounds from insects require toxic solvents, or non ...

Photochemical Aerobic Upcycling of Polystyrene Plastics via Indium Salt‐Mediated Synergistic Catalysis

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
This study presents a practical aerobic photochemical strategy for the upcycling of polystyrene waste, combining bromine radical mediation with InBr3 catalysis. The approach efficiently depolymerizes diverse PS materials under mild conditions, yielding benzoic acid and enabling downstream production of value‐added compounds. The photochemical upcycling

Monomer Sequence Distribution in Butadiene Styrene Copolymers

, 1970
A method is described for determining styrene sequence distribution in butadiene-styrene copolymers. An analog computer is used to resolve overlapped peaks in the styrene aromatic proton NMR spectrum. In n-BuLi copolymers a quite quantitative distinction
