Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
39 words
The process of inhibiting evaporation of fluids from highly absorbent starch-containing polyacrylonitrile graft copolymer, which comprises mixing a higher fatty alcohol of about 12-24 carbon atoms per molecule with said starch-polyacrylonitrile graft copolymer, whereby evaporation of fluid is inhibited.
Claim 2
Dependent Claim
39 words
The process of inhibiting evaporation of fluids from highly absorbent starch-containing polyacrylonitrile graft copolymer, which comprises mixing a higher fatty alcohol of about 12-24 carbon atoms per molecule with said starch-polyacrylonitrile graft copolymer, whereby evaporation of fluid is inhibited.
Claim 3
Dependent Claim
17 words
The process according to claim 1 wherein said higher fatty alcohol contains 16-18 carbon atoms per molecule.
Claim 4
Dependent Claim
31 words
The process according to claim 1 wherein said higher fatty alcohol is applied as an admixture of said higher fatty alcohol, an emulsifying agent, a plant nutrient and an inert carrier.
Claim 5
Dependent Claim
30 words
The process according to claim 1 wherein said higher fatty alcohol is applied as an admixture of said higher fatty alcohol, an emulsifying agent, a fungicide and an inert carrier.
Claim 6
Dependent Claim
25 words
The process according to claim 1 whereby the higher fatty alcohol is applied and admixed with highly absorbent starch-containing polymeric compositions, dry or partially dry.
Claim 7
Dependent Claim
27 words
A process as recited in claim 1, further comprising the step of coating seeds with the mixture of higher fatty alcohol and highly absorbent starch-polyacrylonitrile graft copolymer.
Claim 8
Dependent Claim
36 words
A process as recited in claim 1 further comprising the step of incorporation of the mixture of higher fatty alcohol with the highly absorbent starch-polyacrylonitrile graft copolymer in soil to aid in soil retention of moisture.
Claim 9
Dependent Claim
32 words
A process as recited in claim 1 further comprising the step of using the mixture of higher fatty alcohol with the highly absorbent starch-polyacrylonitrile graft copolymer in humidity control to regulate evaporation.
Claim 10
Dependent Claim
34 words
A process as recited in claim 1 further comprising the step of using the mixture of higher fatty alcohol with the highly absorbent starch-polyacrylonitrile graft copolymer by applying the mixture to cloud seeding compositions.
Claim 11
Dependent Claim
32 words
A process of inhibiting evaporation of water from a starch-polyacrylonitrile graft copolymer comprising mixing said copolymer with a composition selected from the group consisting of alcohols containing 12-24 carbon atoms per molecule.
Claim 12
Dependent Claim
32 words
A process of inhibiting evaporation of water from a starch-polyacrylonitrile graft copolymer comprising mixing said copolymer with a composition selected from the group consisting of alcohols containing 12-24 carbon atoms per molecule.
Claim 13
Dependent Claim
26 words
A water-absorbing evaporation inhibiting composition comprising a highly absorbent starch-polyacrylonitrile graft copolymer composition mixed with a higher fatty alcohol of about 12-24 carbon atoms per molecule.
Claim 14
Dependent Claim
26 words
A water-absorbing evaporation inhibiting composition comprising a highly absorbent starch-polyacrylonitrile graft copolymer composition mixed with a higher fatty alcohol of about 12-24 carbon atoms per molecule.
Claim 15
Dependent Claim
22 words
