The versatile urethane chemistry allows for the production of a wide range of products including flexible and rigid foams, solid elastomers, extrusion parts, coatings, and adhesives. Flexible, high-resilience foamed products include mattresses, upholstered furniture, carpet underlays and auto parts like cushions, backs, and armrests.
Rigid foamed products with a closed cell morphology are used as insulations for commercial and residential buildings.
Other applications of rigid foam include insulations for tanks, pipes, water heaters, refrigerators, and freezers.
Examples of solid elastomeric products are durable elastomeric wheels and tires for forklifts, skateboards, roller coasters and escalators. Elastomeric urethanes find also many uses in the automotive industry. Some examples are bumpers, fenders, steering wheels, instrument and door panels, and gaskets for trunks, windows and windshields.
Polyurethanes are also used as electrical potting compounds, adhesives, coatings, sealants, and for the fabrication of synthetic fibers (Spandex).
Triolo was born and raised in South Philadelphia. He received his BS in chemistry from St. Joseph College and his PhD in organic synthesis from the University of Pennsylvania in 1958. During two summers of graduate school at Penn, he worked at the Philadelphia Naval Base in the High Polymer Lab.
The regioselective preparation of 2,5-disubstituted pyrroles, useful structural scaffolds, is important. To this end, a protocol based on a stepwise iododesilylation and a subsequent coupling reaction, involving a 6-step pathway starting from the simplest pyrrole, has been realised. This methodology can be widely used in the synthesis of drugs, molecular wires, and high-molecular-weight polymers.
