they are of little value as pressure sensitive adhesives (col.
4, lines 29-33).
Bartissol discloses a process for making water soluble,
high molecular weight polymers and copolymers for use as
flocculants for water treatment (col. 1, lines 9-13). All of
the disclosed monomers for use in the process (col. 3, lines
31-37) differ from those used by Martens. The polymerization
takes place in aqueous solution, and the radiation used for
the polymerization has a wavelength of 300-450 nm and a mean
intensity of 20 to 2,000 watts/m2 (2 to 200 mW/cm2) and is
applied in an increasing manner (col. 3, lines 15-26).
Yada discloses a process for preparing an acrylic polymer
having excellent water solubility and high molecular weight,
and states that such polymers are used as paper sizing agents,
viscosity builders, waste water treating agents and
precipitants
for ores (col. 1, lines 13-16). Yada’s process produces
cationic polymers which are either a homopolymer of a cationic
