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 C1-6alkyl (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.
