Acrylamide (AMD) is the basic
monomeric unit used in the production
of a major class of water soluble
polymers, generically termed polyacrylamides
(PAMs). The structural
formula of AMD is shown in Fig. 1.

Under the proper conditions and with
suitable catalysts, AMD can polymerize
with other molecules of AMD, or
with other vinyl monomers to yield
products with extremely high molecular
weights. PAMs with molecular
weights in excess of 10 million,
i.e. with chain lengths of more than
105,000 monomeric units, are produced
commercially. By utilizing the
appropriate comonomers or by postreaction
with other reagents, these
polymers may be cationic, nonionic.
or in the case of those used to control
soil erosion, anionic. The anionic reaction
product of AMD and a salt of
acrylic acid is shown in Fig. 2. The
same chemical structure can also be
produced by hydrolysis of the nonionic
homopolymer of AMD or by
hydrolysis of polyacrylonitrile.
