标题 :Urethanes containing two perfluoroalkylthio groups
发明人：DEAR ROBERT ERNEST ARTHUR; FALK ROBERT ALLAN
权利人:CIBA GEIGY CORP
摘要:Perfluoroalkylthio glycols and esters thereof can be prepared by the free-radical catalyzed addition of a perfluoroalkylthiol to an acetylenic alcohol or ester thereof. The compounds obtained are useful intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. In one embodiment, a perfluoroalkylthio glycol can be reacted with a diisocyanate to obtain a polyurethane containing perfluoroalkylthio groups, which polyurethanes are useful as coatings to provide oil and water repellence to textiles and as additives to plastics to provide mold-release and other desirable properties.

标题:Dynamic urea bonds for reversible and self-healing polymers
发明人：CHENG JIANJUN; YING HANZE
权利人:UNIV ILLINOIS
摘要:The disclosure provides reversible polymers from polyurea by modifying the nitrogen atom with hindered substituents. The reversibility of hindered urea bond (HUB) can be controlled by changing the bulkiness of the substituents, and N-tert-butyl-N-ethylurea (TBEU), with its high binding constant and short lifetime, is applicable in the design of reversible polymer and self-healing materials at mild temperatures without external stimuli. HUB can be used in the design of smart materials with its adjustable reversibility, facile synthesis, and compatibility with many other polymer structures.

标题 :Conductive polyurethane-urea/polyethylene oxide polymer

摘要:A water reaction synthesis with polyoxyethylene diol, diisocyanate and dibutyltin bis lauryl mercaptide produces a high molecular weight thermoplastic polyurethane-urea linear polymer with surface resistivity 1011-106 ohm/sq. Thermoplastic and/or elastomeric antistatic compositions containing other melt processable polymers and/or filler, and the polymer exhibit permanent protection. Antistatic protection can be increased when the polymer complexes with a metal salt such as lithium chloride, or lithium acetate. The composition is useful in the manufacture of antistatic floor coverings and textile texturing and drafting elements such as cots and aprons.
