Appeal No. 2003-0515
Application 09/296,216
APPENDIX
1. A conformance additive comprising a dry mixture of water
soluble crosslinkable polymer, a crosslinking agent, and a
reinforcing material selected from among fibers and comminuted
plant materials.
2. The additive of claim 1 wherein the polymer is an a (sic)
carboxylate-containing polymer and the crosslinking agent is
a chromic carboxylate complex.
3. The additive of claim 2 wherein the reinforcing material
comprises hydrophilic and hydrophobic fibers.
4. The additive of claim 3 wherein the hydrophobic fibers
comprise at least one selected from the group of hydrophobic
fibers consisting essentially of nylon, rayon, and hydrocarbon
fibers, and wherein the hydrophilic fibers comprise at least one
selected from the group of hydrophilic fibers consisting
essentially of glass, cellulose, carbon, silicon, graphite,
calcined petroleum coke, and cotton fibers.
5. The additive of claim 2 wherein the reinforcing material
comprises comminuted plant material.
6. The additive of claim 5 wherein the reinforcing material
comprises at least one comminuted material selected from the
group of comminuted plant materials consisting essentially of nut
and seed shells or hulls of almond, brazil, cocoa bean, coconut,
cotton, flax, grass, linseed, maize, millet, oat, peach, peanut,
rice, rye, soybean, sunflower, walnut, and wheat; rice tips; rice
straw; rice bran; crude pectate pulp; peat moss fibers; flax;
cotton; cotton linters; wool; sugar cane; paper; bagasse; bamboo;
corn stalks; sawdust; wood; bark; straw; cork; dehydrated
vegetable matter; whole ground corn cobs; corn cob light density
pith core; corn cob ground woody ring portion; corn cob chaff
portion; cotton seed stems; flax stems; wheat stems; sunflower
seed stems; soybean stems; maize stems; rye grass stems; millet
stems; and mixtures thereof.
7. The additive of claim 2 wherein the polymer is a partially
hydrolyzed polyacrylamide.
