Rigid Polyurethane Foams

In this work, the research results of the synthesis and properties of the polyols with the oxamidoester group, obtained in the reaction of N-substituted morpholine-2,3-dione derivatives with excess of alkylene carbonates have been presented. Using these derivatives as polyol components, rigid foamed polyurethane materials of high thermal stability and mechanical strength have been obtained. New polyurethane foams obtained using hydroxypropyl morpholine-2,3-dione derivatives can be used as heat-insulating materials of operating temperature as high as 150°C.

Trade Offs

Three types of seemingly unyielding trade-offs have continued to challenge the rational design for circular polymers with both high chemical recyclability and high-performance properties: depolymerizability/performance, crystallinity/ductility, and stereo-disorder/crystallinity. Here, we introduce a monomer design strategy based on a bridged bicyclic thiolactone that produces stereo-disordered to perfectly stereo-ordered polythiolactones, all exhibiting high crystallinity and full chemical recyclability. These polythioesters defy aforementioned trade-offs by having an unusual set of desired properties, including intrinsic tacticity-independent crystallinity and chemical recyclability, tunable tacticities from stereo-disorder to perfect stereoregularity, as well as combined high-performance properties such as high thermal stability and crystallinity, and high mechanical strength, ductility, and toughness.
