标 题:Process for the preparation of polyamines from N-monoaryl-N',N'-dialkyl urea compounds and their use for the synthesis of polyurethanes
发明人：RASSHOFER WERNER; GROEGLER GERHARD
权利人:BAYER AG
摘要:This invention relates to an improved process for the preparation of aromatic polyamines containing urethane and/or biuret and/or urea and/or isocyanurate groups and preferably also ether groups by the hydrolysis of poly-N-monoaryl-N',N'-dialkyl urea compounds (1-aryl-3,3-dialkyl ureas). The ureas are obtained by the reaction of secondary aliphatic, cycloaliphatic or saturated heterocyclic amines with divalent to tetravalent isocyanate compounds containing isocyanate end groups attached to aromatic residues. The ureas correspond to the general formula: wherein R1, R2 denote alkyl or cycloalkyl groups, or together form a ring and A denotes a divalent to tetravalent residue attached to the ureas by aromatic groups. Hydrolysis is carried out in the presence of water and up to two equivalents of a base containing hydroxide ions and/or up to two equivalents of a compound containing tertiary amino groups, optionally in the presence of solvents. The use of the polyamines obtained by this process for the synthesis of polyurethanes is also described.

权利人:ASPEN AEROGELS INC
摘要:The present invention discloses novel porous polymeric compositions comprising random copolymers of amides, imides, ureas, and carbamic-anhydrides, useful for the synthesis of monolithic bimodal microporous/macroporous carbon aerogels. It also discloses methods for producing said microporous/macroporous carbon aerogels by the reaction of a polyisocyanate compound and a polycarboxylic acid compound, followed by pyrolytic carbonization, and by reactive etching with CO2 at elevated temperatures. Also disclosed are methods for using the microporous/macroporous carbon aerogels in the selective capture and sequestration of carbon dioxide.

标题 :Synthesis of vinyl polymers by controlled radical polymerization
发明人：WHITE DANIELA; O'DWYER JAMES B
权利人:PPG IND OHIO INC
摘要:A controlled free radical polymerization process, which includes the steps of: adding a monofunctional iniferter compound to an oxygen-free solvent; heating the solution to a temperature sufficient to allow the iniferter compound to form two carbon centered radical residues; adding a first monomer composition comprising one or more monomers to the solution containing the radical containing residues; polymerizing the first monomer composition to form a quasi-living polymer; and optionally polymerizing a second monomer composition comprising one or more monomers, which are different than the first monomer composition. The resulting non-random copolymer having the general formula:n nφ-[-A p -B s -] t -φn nwhere A and B are different compositions of ethylenically unsaturated monomers; p is an integer from 1 to 1,000; s is an integer from 0 to 1,000; t is an integer from 1 to 100; and φ is a residue from the iniferter.

权利人:VENUS MEDTECH HANGZHOU INC
摘要:The present application discloses an implantable material and a synthesis method therefor and a prosthetic heart valve. The implantable material uses polyurethane, the molecular chain structure of polyurethane comprises a soft segment and a hard segment, and a functional branched chain is grafted onto the hard segment; the solubility parameter of the functional branched chain is 6-8. According to the present application, by introducing the functional branched chain into the hard segment, the compatibility between the hard segment and the soft segment is improved and the stress transfer points between the hard segment and the soft segment are increased, so that the prepared implantable polymer material has excellent mechanical properties.
