Reaction of trichloroacetyl isocyanate with arylacetylenes [PDF]

, 1973
1. Trichloroacetyl isocyanate reacts with the p-CH3- and p-CH3O-substituted and unsubstituted phenylacetylenes and certain tolanes of the 2,4-cycloaddition type, with the formation of 1,3-oxazin-4-one derivatives. 2. A thermographic study of the reaction

Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

Journal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Effect of Hydroxyl‐Terminated Polybutadiene Grade on Rheology and Settling of High‐Solids Mixtures of Mock Propellants

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The most common binder used in composite rocket propellants is based on the pre‐polymer hydroxyl‐terminated polybutadiene (HTPB). It has been shown to have excellent mechanical properties and a long life once crosslinked, and studies have examined the kinetics of crosslinking and pot life of energetic formulations with HTPB.

Highly integrated, alignment healing, and full‐recyclable multifunctional flexible devices based on dynamic covalent bonds

Smart Molecules, EarlyView.
This study addresses stability, repair, and recycling in flexible devices using polymers with identical dynamic bonds but incompatible backbones. This enables robust integration, precise self‐healing, and full recyclability. We demonstrate optoelectronic sensors that, after damage, magnetically self‐assemble and heal upon heating.

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.
