权利人:NEWSOUTH INNOVATIONS PTY LTD
摘要:The present disclosure relates to the field of synthesis of block copolymers, and polymeric nanofibers having a core-shell morphology produced therefrom. The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.

标题:Synthesis of pseudopterosin compounds
发明人：COREY ELIAS J
权利人:HARVARD COLLEGE
摘要:The present invention is directed to a new synthetic route to pseudopterosin aglycone (3): n a key intermediate for the synthesis of a group of antiinflammatory natural products including pseudopterosin A (1) and E (2). The pathway of synthesis starts with the abundant and inexpensive (S)-(−)-limonene and its long-known cyclic hydroboration product (4) and leads to the chiral hydroxy ketone (6). Conversion of (6) to (10) followed by a novel aromatic annulation produced (15) which underwent highly diastereoselective cyclization to afford the protected pseudopterosin aglycone (16). The naturally occurring pseudopterosins such as (1) and (2) are readily available from this key intermediate.

标题:Synthesis of dithioester chain transfer agents and use of bis(thioacyl) disulfides or dithioesters as chain transfer agents
发明人：RIZZARDO ENZIO; THANG SAN HOA; MOAD GRAEME
权利人:E I DUPONT NEMOURS AND COMPANY; COMMW SCIENT IND RES ORG
摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.

标题 :Process for synthesis of polymer compositions, polymer compositionS obtainable by the process, and use of the same
发明人：ROOS SEBASTIAN; EISENBERG BORIS; HARPE CAROLIN
权利人:ROHMAX ADDITIVES GMBH
摘要:The present invention relates to a process for synthesis of polymer compositions with reduced catalyst content, wherein ethylenically unsaturated monomers containing less than 0.5 wt % of ethylenically unsaturated monomers with at least one carboxylic group, sulfonic acid group and/or at least one phosphonic acid group relative to the total weight of the ethylenically unsaturated monomers are polymerized by means of initiators containing a transferable group of atoms and of one or more catalysts comprising at least one transition metal in the presence of ligands which can form a coordination compound with the metal catalyst or catalysts and, after the polymerization, the catalyst contained in the polymer is at least partly separated. For this purpose, the polymer composition is filtered, after the polymerization, in the presence of at least one filter aid which contains at least 0.5 wt %, relative to the total weight of the filter aid, of repeating units that contain at least one carboxylic acid group, sulfonic acid group and/or at least one phosphonic acid group.
