标题:Unsaturated ester-amides of halogenated alkenes
发明人：D ALELIO GAETANO F
权利人:ALELIO GAETANO F D
摘要:This invention deals with new unsaturated esteramides of alpha , beta -unsaturated polycarboxylic acids derived from halogenated alcohols of the formula wherein R is a divalent hydrocarbon moiety having at least one and no more than 10 carbon atoms, X is a member selected from the class of bromine and chlorine, and R' is a member selected from the class of hydrogen, X and a monovalent hydrocarbon containing at least one and no more than 20 carbon atoms. Typical esteramides are the maleates, fumarates, itaconates and citraconates. These monomers possess fire-retardant properties and are useful for the synthesis of polymers and copolymers.

摘要:Unsaturated polyesters e.g. poly (ethylene glycol fumarate) (PEGF) were developed as new coating materials for iron oxide nanoparticles. Different strategies were adopted in their synthesis to provide different characteristics including solubility, molecular weight and structure also degrees of unsaturation. After synthesis of the nanoparticles; the material was applied as a coating on them. These materials were applicable without further processing, however, coatings were cured via thermal, redox or photo initiated crosslinking on the nanoparticles to provide rigid shells on the surface of nanoparticles.

标题 :Perfluoroalkyl alcohols
发明人：KLEINER EDUARD K; FALK ROBERT A
权利人:CIBA GEIGY CORP
摘要:Perfluoroalkyl group containing alcohols are disclosed with utility as intermediates for the synthesis of oil and water repellent fluorochemicals. The alcohols are obtained by the addition of mercaptoalcohols to perfluoroalkyl group containing esters of fumaric, maleic, citraconic, mesaconic, itaconic, methylene malonic or aconitic acids.
