专利号:US-5458796-A 优先权日:1994-03-31 标 题 :Synthesis of polyisobutylene star-branched polymers via living carbocationic polymerization 发明人:STOREY ROBSON F; DUBOIS DONN A; HANDLIN JR DALE L; CHISHOLM BRET J 权利人:SHELL OIL CO 摘要:The present invention is the synthesis of star polymers containing polyisobutylene (PIB) via the arm-first, core-last method. These polymers are superior in properties to known hydrogenated polyisoprene star-branched polymers due to their inherent lack of unsaturation.
专利号:US-5420237-A 优先权日:1991-08-29 标 题:Enzymatic synthesis of polyaniline 发明人:ZEMEL HAYA; QUINN JOHN F 权利人:ALLIED SIGNAL INC 摘要:This invention relates to a process for the enzymatic synthesis of electrically conductive substituted and unsubstituted polyanilines. Aniline monomer(s), an oxidizing agent, which comprises an enzyme and an electron acceptor, and an acidifying agent are reacted together to form polyanilines.
专利号:US-5840814-A 优先权日:1996-08-07 标题 :Multi-arm star polymers having a well-defined core and methods for the synthesis thereof 发明人:MAJOROS ISTVAN J; MARSALKO TIMEA M; KENNEDY JOSEPH P 权利人:UNIV AKRON 摘要:The synthesis of star polymers having well-defined arms emanating from well-defined and readily controllable calix n!arene (n=4 to 16) cores are described. The synthesis is particularly suitable for polyisobutylene and/or polysiloxane star polymers. The synthesis has been achieved using carbocationic and/or anionic ring-opening polymerization techniques to form polymer arms of desired molecular weights, then separately preparing the calixarene derivative core, and finally, linking the arms to the core by transesterification or hydrosilation.
专利号:US-7129197-B2 优先权日:2001-08-31 标题 :Synthesis of poly-alpha olefin and use thereof 发明人:SONG WEI; HEILMAN WILLIAM J 权利人:SHELL OIL CO 摘要:One or more oligomers of an olefin are prepared in the presence of a single-site catalyst. Preferably, the olefin is an α-olefin, and the oligomers are a poly-alpha-olefin (PAO). The PAO so prepared is completely or substantially free of tertiary hydrogen resulting from isomerization. Consequently, the PAO possesses improved biodegradability, improved oxidation resistance, and/or a relatively higher viscosity index. The PAO has many useful applications, such as a component of a lubricant.
