标题:Facile synthesis of symmetric esters of alkylenebisphosphonic acids
发明人：HERLINGER ALBERT W; STEPINSKI DOMINIQUE C
权利人:UNIV LOYOLA CHICAGO
摘要:A facile synthesis of symmetric esters of C 1 -C 10 alkylenebisphopsphonic acids is disclosed in which a C 1 -C 10 alkylenebis(phosphonic dichloride) is reacted with an alcohol in the presence of a catalytic amount of 1H-tetrazole and a base in an aprotic solvent to form a first reaction mixture. The first reaction mixture is maintained for a time period sufficient to form a C 1 -C 10 alkylenebis(chloro ester phosphonate) that is reacted under basic conditions with an excess of a hydroxylated compound to form a second reaction mixture that is itself maintained for a time period sufficient to form a C 1 -C 10 alkylenebis(ester phosphonate) partial ester, homoleptic tetraester or mixed tetraester. The material so formed can be recovered or used as is.

标 题 :Disentangled ultra-high molecular weight polyethylene, methods of making and using
发明人：RASTOGI SANJAY; ROMANO DARIO; GOTE RAVINDRA

摘要:Disclosed herein are methods for synthesis of ultra-high molecular weight polyethylene (UHMWPE), with improved disentanglement, for solid-state processing into a product, such as tapes, films, and ropes, etc., with superior mechanical properties. The method includes using a catalyst support which includes MgCl 2 pre-reacted with different alcohols. The MgCl 2 /alcohol adducts are reacted with different aluminum alkyls to form nanoparticles support, preferably in-situ, under inert environment in the presence of the monomer used to synthesize the UHMWPE. The resulting heterogeneous catalytic system and polymer synthesis method results in improved UHMWPE with high average molecular weight (Mw)>1 million g/mol, with lower levels of entanglement (while avoiding fouling seen with homogenous catalytic systems), allowing for processing into products such as tapes with superior mechanical properties.

标 题 :Process for the Synthesis of Amine Ethers
发明人：FREY MARKUS; BROENNIMANN VALERIE
权利人:CIBA GEIGY CORP
摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.

发明人：GALBO JAMES P; DETLEFSEN ROBERT E; DIFAZIO MICHAEL P; GRACE HENRY C; KUELL CHRISTOPHER
权利人:CIBA SC HOLDING AG
摘要:N-(Hydroxyalkoxy) hindered amine stabilizers are prepared by reacting the corresponding N-oxyl compound with a peroxide or organic hydroperoxide and a catalytic amount of a metal salt or metal-ligand complex in an alcohol solvent. These N-(hydroxyalkoxy) hindered amines are particularly useful as stabilizers for polyolefins, thermoplastic polyolefins and automotive coating compositions.

标 题:Synthesis of molybdenum oxide/alkanol complexes
发明人：MARQUIS EDWARD T; SANDERSON JOHN R; KEATING KENNETH P; SMITH WILLIAM A

摘要:Storage stable solutions of molybdenum/alkanol complexes in the alkanol are prepared by reacting a molybdenum oxide and ammonium hydroxide and an amount of a straight chain or branched chain C6-C13 alkanol, within the range of about 10 to about 55 moles of alkanol per gram atom of molybdenum sufficient to form a storage stable molybdenum/alkanol complex. The complex-forming reaction is initiated in the presence of about 1 to about 4 moles of water per gram atom of molybdenum and about 0.5 to about 10 moles of ammonia per gram atom of molybdenum, the water and ammonia preferably being added in the form of concentrated ammonium hydroxide. The reaction is conducted at a temperature of about 120 DEG to about 190 DEG C. for a period of time, normally about 3 to about 8 hours, sufficient to substantially completely remove ammonia and water to provide a liquid reaction product comprising said solution of molybdenum/alkanol complex dissolved in unreacted alkanol and containing about 0.001 to about 0.1 wt. % of water. The reaction product is filtered to provide a clarified storage stable solution of the molybdenum/alkanol complex having a dissolved molybdenum content of about 3 to about 10.5 wt. %.
