专利号:US-9951096-B2 优先权日:2008-08-22 标 题 :Catalysts and methods for polymer synthesis 发明人:ALLEN SCOTT D; CHERIAN ANNA E; SIMONEAU CHRIS A; FARMER JAY J; COATES GEOFFREY W; GRIDNEV ALEXEI; LAPOINTE ROBERT E 权利人:SAUDI ARAMCO TECH CO 摘要:The present invention provides unimolecular metal complexes having increased activity in the copolymerization of carbon dioxide and epoxides. Also provided are methods of using such metal complexes in the synthesis of polymers. According to one aspect, the present invention provides metal complexes comprising an activating species with co-catalytic activity tethered to a multidentate ligand that is coordinated to the active metal center of the complex.
专利号:US-6521707-B2 优先权日:2000-11-06 标 题:Isocyanates containing amino groups 发明人:PODSZUN WOLFGANG; KRUEGER JOACHIM; KARLOU-EYRISCH KAMELIA 权利人:BAYER AG 摘要:The invention relates to novel isocyanates containing tertiary amino groups, a process for preparing them, and also their use for the synthesis and modification of polymers. The invention provides isocyanates of the formula (I) n where n R 1 and R 2 are, independently of one another, alkyl having from 1 to 6 carbon atoms, where R 1 and R 2 may be joined to form a ring, n Z is alkylene having from 2 to 6 carbon atoms, n n is an integer from 0 to 20, n Y is alkylene having from 2 to 6 carbon atoms. n The alkyl radicals R 1 and R 2 may be linear or branched or joined to form an aliphatic ring. The alkylene radical Z preferably contains from 2 to 4 carbon atoms.
