Photopolymerization of Monomer-Containing Deep Eutectic Solvents

Log−Log plot graphic of initial rate versus light intensity of deep eutectic solvent (DES) monomers photopolymerizationThe kinetics of photopolymerization in deep eutectic solvents (DESs) is investigated through RT‐FTIR. The systems of this study are choline chloride DESs made of acrylic acid and methacrylic acid (DES monomers) and a nonreactive analog isobutyric acid.  Analysis of the evolution of conversion indicates dramatic increase in polymerization rate when comparing the polymerization of the DES monomers to pure monomer polymerization. A significant increase in polymerization rate is also seen in the systems that include a methyl ester derivative of the hydrogen bond donor monomer in a nonpolymerizable DES.

Cationic Cobalt(II) Bisphosphine Hydroformylation Catalyst

Hydroformylation catalyst

Hydroformylation is one of the highest-volume homogeneously catalyzed industrial processes today. One segment of the market deals with unreactive alkenes that require the most active cobalt or rhodium-based catalysts that need high pressures (> 200 atm) to prevent decomposition of the catalysts. A new class of cationic cobalt bisphosphine hydroformylation catalysts exhibit exceptional activity under medium pressure conditions and remarkable stability with respect to cobalt-induced phosphine degradation reactions or decomposition to cobalt metal.

The capacity of frontal polymerization as a coating strategy for wood substrates was studied. Results indicate resin viscosity and film thickness critically affect the qualitative and quantitative propagation of the thermal front resulting in the formation of the coating.
