  • Vinyl sulphone modified polymer
    Patent number: 7183367
    Abstract: There is provided a polymer having a side chain of general formula (I) in which R may be any suitable alkyl, oxyalkyl, aryl or oxyaryl linking group R is preferably C1-6 alkyl (especially —CH2—), a benzene group or a group —CH2—O-Phe-. Generally, the side chain will be attached to an ethylene moiety forming part of the backbone of the polymer. Preferred polymers include polystyrene. The polymer is useful as a support for solid phase chemical reactions especially combinatorial chemical synthesis.
    Type: Grant
    Filed: March 12, 2004
    Date of Patent: February 27, 2007
    Assignee: N.V. Organon
    Inventors: David Gani, Friedrich E. Kroll, Michael J. Plater, John R. Morphy, David C. Rees
