ABSTRACT:
A method for cyclization and reversal of the polarity of polymers on a substrate. The method provides for the formation of a polymer on a substrate (2) with a tether molecule (4). Through unmasking of a protective group (PG.sub.2) a cyclic polymer (6) is formed. Through cleavage of an appropriate bond, a polarity reversed polymer (8) is formed. The method finds particular application in the formation of, for example, peptides and oligonucleotides.
