Historical note:
CETI has been mentioned - and their plastic beads. Everyone assumed
the beads were inactive and merely provide a neutral substrate. But
were they?
Patterson used ordinary water instead of the usual heavy water and
palladium-coated plastic beads as a cathode. Not sure Patterson
ever divulged which plastic was used.
check US Pat. 5,580,838, December 3, 1996.

His patent mentions "cross-linked polystyrene". "As disclosed in
U.S. Pat. No. 5,036,031 and 4,943,355, in a column exchange, a
copolymer in hydrogen form is reacted with chlorosulfonic acid, the
resulting microspheres have a sulfonate surface in the hydrogen form.
The sulfonated microspheres are next placed in an aqueous copper
chloride solution. The microspheres have copper salts on the surface
and hydrochloric acid is contained in the solution by ion exchange."
"Cross-linked polystyrene copolymer is reacted in a column exchange
with chlorosulfonic acid yielding sulfonated cross-linked polystyrene
copolymer microspheres having hydrogen ions on the outer layer and
hydrochloric acid, as shown in FIG. 1 of my U.S. '031. This
sulfonation should be limited to a 100 molecular layer depth. If
sulfonation is excessive, the diameter of the microspheres will
change when dry microspheres are hydrated."
