WATER-SOLUBLE POLYMERS............Government
regulations related to water treatment, the search for energy sources,
product quality improvements, economizing on raw materials -- all these
are driving forces for the use of water-soluble polymers.
Water-soluble polymers,
both synthetic and those derived from natural products are useful as
flocculants, water-absorbing agents, viscosifiers, dispersants, etc.
The markets under investigation in this study are: superabsorbents,
water treatment, petroleum recovery, paper additives and mineral
processing.

|
FUNCTION |
| |
|
|
SUPERABSORBENTS |
Absorption of body
fluids in hygiene products. Retention of water in
horticultural/agricultural applications |
| |
End Uses: Diapers,
feminine hygiene products,
agriculture, other. |
| |
|
|
WATER
TREATMENT |
Clarify influent and
effluent waters; condition and disposal of the waste sludge
formed. |
| |
End Uses: Municipal water treatment,
waste water
treatment, sludge control and industrial
water treatment and waste water
treatment. |
| |
|
|
PAPERMAKING ADDITIVES |
Principally for dry and wet strength; other
applications include retention, drainage, savealls, and
clarification. |
| |
End Uses: Wet
strength resins, dry strength resins,
retention, drainage, savealls, liquor
clarification. |
| |
|
|
PETROLEUM RECOVERY |
Water-soluble
polymers are utilized in seven steps in the recovery of oil;
drilling muds, cementing, workover and completion, fracturing,
antiscalant, and flooding. They function as thickeners and
fluid-loss control agents. |
| |
End Uses: Drilling
fluids (muds), cementing,
workover and completion fluids, acidizing,
fracturing, antiscalant, enhanced oil
recovery. |
| |
|
|
MINERAL
PROCESSING |
Flocculants are
utilized mainly as thickening and clarification agents. |
| |
End Uses: Coal, iron
ore, clay, soda ash, uranium,
potash, bauxite, copper, titanium dioxide,
calcium carbonate, zinc and lead, gold
and silver. |
