Ultrahigh Tg Epoxy Thermosets Based on Insertion Polynorbornenes
Macromolecules, Article ASAP. DOI: 10.1021/acs.macromol.5b02648
Thermosetting materials (thermosets) are widely used organic materials derived from 3D-network forming monomers. Achieving high glass transition temperature (Tg) thermosets is often a challenging task due to the complexity of designing efficiently and cheaply monomers which are rigid enough to prevent molecular motions within the thermoset. We report here a very simple route to prepare epoxy thermosets with Tg as high as 350 °C, based on insertion polynorbornenes. The epoxy monomer…
Thermosetting materials (thermosets) are widely used organic materials derived from 3D-network forming monomers. Achieving high glass transition temperature (Tg) thermosets is often a challenging task due to the complexity of designing efficiently and cheaply monomers which are rigid enough to prevent molecular motions within the thermoset. We report here a very simple route to prepare epoxy thermosets with Tg as high as 350 °C, based on insertion polynorbornenes. The epoxy monomer (PNBE(epoxy)) is prepared by the epoxidation of poly(5-vinylnorbornene) obtained by catalytic insertion polymerization of 5-vinylnorbornene. PNBE(epoxy) can be cross-linked with simple biosourced compounds. Alternatively, polar insertion polynorbornene can also be used as cross-linker in the formulation of an epoxy resin, once again resulting in epoxy resins with Tg higher than 300 °C and devoid of degradation at this temperature. Thus, this study clearly demonstrates the viability of catalytic polymerization to access epoxy thermosets with ultrahigh Tg.

“Techno-economics of microalgae production and conversion to refinery-ready oil with co-product credits”
Biofuels, Bioprod. Bioref. 9:760–777 (2015); DOI: 10.1002/bbb.1610
The economics of the production of hydrotreated algal oil (HTAO) along with co-production
of animal feed and nutraceuticals (omega-3 oils) was explored. Base case calculations were for commercial scale production of 10,000 barrels per day of HTAO with nutraceuticals claiming only 0.05% of the raw algae oil (AO). The sensitivity of economics to critical parameters was studied.We
gratefully acknowledge that this work was funded by DOE contract DE-EE0006063.Other authors -
“Ortho-Phosphinobenzenesulfonate: A Superb Ligand for Palladium-Catalyzed Coordination-Insertion Copolymerization of Polar Vinyl Monomers,”
Acc. Chem. Res., 2013, 46, 1438. DOI: 10.1021/ar300256h
Ligands, Lewis bases that coordinate to the metal center in a complex, can completely change the catalytic behavior of the metal center. In this Account, we summarize new reactions enabled by a single class of ligands, phosphinesulfonates (ortho-phosphinobenzenesulfonates). Using their palladium complexes, we have developed four unusual reactions, and three of these have produced novel types of polymers.
