标 题:Methods for the synthesis of di(hydroxymethyl)tetrahydrofuran and its application in polyesters and polyurethanes
发明人：SPIEGELBERG BRIAN; BRANDT ADRIAN; BECK HORST; KUX ALEXANDER; TIN SERGEY; DE VRIES JOHANNES GERARDUS
权利人:HENKEL AG & CO KGAA
摘要:The present invention relates to the synthesis of di(hydroxymethyl)tetrahydrofuran (DHMTHF) and the preparation of trans-enriched mixtures of DHMTHF. The invention further refers to polyester polyols which are obtained by reaction of cis/trans DHMTHF mixtures with a dicarboxylic acid. The invention further relates to polyurethanes and compositions containing a polyester polyol comprising DHMTHF, in particular to such polyurethane-containing (adhesive) compositions.

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.

标题:Process for the synthesis of silylated polyurethanes and silylated polyurethane composition
发明人：LAFERTE OLIVIER
权利人:BOSTIK SA
摘要:The present invention provides a process for the synthesis of silylated polyurethanes, comprising three sequential steps, a step (i) of preparing NCO-terminated polyurethane, a step (ii) of partial grafting of the NCO functions with silane functions and a step (iii) of total grafting of the residual NCO functions with functions that react with the NCO functions by means of polyfunctional compounds. The present invention also provides a silylated polyurethane composition that can be obtained by means of the process according to the invention, an adhesive composition comprising said silylated polyurethane composition and a self-adhesive item obtained from the adhesive composition according to the invention.

标 题 :Process for the synthesis of N-(hydroxyalkoxy) substituted hindered amine stabilizers
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.
