Application 08/898,627
Claims 16 and 22 are representative of the subject matter on appeal and read as
follows:
16. A containerization system comprising a water dispersible gel contained in a
water-soluble or water-dispersible bag, the water dispersible gel being obtained by a
method comprising mixing:
(a) 1-60% by weight of an ionic, water-soluble agrochemical;
(b) 1-4% by weight of a crosslinked polyacrylic acid;
(c) 30-80% by weight of water; and, finally,
(d) 2-20% by weight of a base;
the water dispersible gel having pH in the range 6 to 10, a storage modulus (G')
in the range 20-500 Pa and a Tan * of less than 0.5.
22. A containerization system comprising a water dispersible gel contained in a
water-soluble or water-dispersible bag, the water dispersible gel comprising:
(a) an ionic, water-soluble agrochemical;
(b) the reaction product of a crosslinked polyacrylic acid and a base; and
(c) 30-80% by weight of water;
wherein the water dispersible gel has a pH in the range 6 to 10, a storage
modulus (G') in the range 20-500 Pa and a Tan * or less than 0.5.
