A method for at least temporarily retaining moisture in a soil-based substrate includes applying an acrylamide pyranose polymer to the soil-based substrate.
대표청구항▼
1. A method for at least temporarily retaining moisture in a soil-based substrate, the method comprising applying an acrylamide pyranose polymer to the soil-based substrate; wherein the acrylamide pyranose polymer comprises repeat units represented as: wherein each R is individually H or C1-C8 alkyl
1. A method for at least temporarily retaining moisture in a soil-based substrate, the method comprising applying an acrylamide pyranose polymer to the soil-based substrate; wherein the acrylamide pyranose polymer comprises repeat units represented as: wherein each R is individually H or C1-C8 alkyl. 2. The method of claim 1, wherein the applying comprises applying one or more of beads, pellets, chunks and particles comprising the acrylamide pyranose polymer. 3. The method of claim 2, wherein the particles are a size of about 10 μm to about 100 μm. 4. The method of claim 1, wherein the applying comprises one or more of spraying, dusting, atomizing and sprinkling a solid, solution, or suspension comprising the acrylamide pyranose polymer onto the soil-based substrate. 5. The method of claim 1, wherein the applying comprises mixing the acrylamide pyranose polymer into the soil-based substrate. 6. The method of claim 1, wherein the acrylamide pyranose polymer is in a solution, a suspension, or a gel. 7. The method of claim 6, wherein the solution of the acrylamide pyranose polymer comprises about 0.001% to about 90% by mass of the acrylamide pyranose polymer. 8. The method of claim 1, wherein the soil-based substrate comprises one or more of a soil substrate, a topsoil substrate, a subsoil substrate, a potting soil substrate, a mud substrate, a clay substrate, a sand substrate, a gravel substrate, a rock substrate, a stone substrate, a concrete substrate, a cement substrate, and an asphalt substrate. 9. The method of claim 1, wherein each R is individually H or methyl. 10. The method of claim 1, wherein each R is individually H, methyl, ethyl, propyl, isopropyl, n-butyl, sec-butyl, tert-butyl, n-pentyl, n-hexyl, n-heptyl, n-octyl, 2-ethylhexyl, or isomers thereof. 11. The method of claim 1, wherein the acrylamide pyranose polymer further comprises a monomer that is an acrylamide or a (meth)acrylate. 12. The method of claim 11, wherein the monomer is selected from acrylamide, methyl methacrylate, ethyl methacrylate, n-propyl methacrylate, n-butyl methacrylate, isopropyl methacrylate, isobutyl methacrylate, n-amyl methacrylate, n-hexyl methacrylate, isoamyl methacrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate, sec-butyl methacrylate, tert-butyl methacrylate, 2-ethylbutyl methacrylate, cinnamyl methacrylate, cyclohexyl methacrylate, cyclopentyl methacrylate, 2-ethoxyethyl methacrylate, furfuryl methacrylate, 3-methoxybutyl methacrylate, 2-methoxybutyl methacrylate, n-octyl-methacrylate, 2-ethylhexyl methacrylate, methyl acrylate, ethyl acrylate, n-propyl acrylate, n-butyl acrylate, isopropyl acrylate, isobutyl acrylate, n-amyl acrylate, n-hexyl acrylate, isoamyl acrylate, 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, sec-butyl acrylate, tert-butyl acrylate, 2-ethylbutyl acrylate, cinnamyl acrylate, cyclohexyl acrylate, cyclopentyl acrylate, 2-ethoxyethyl acrylate, furfuryl acrylate, 3-oxybutyl acrylate,2-oxybutyl acrylate, n-octyl-acrylate, or 2-ethylhexyl acrylate. 13. The method of claim 1, wherein applying the acrylamide pyranose polymer occurs in the presence of water. 14. The method of claim 1, wherein the method further comprises applying an additive to the soil-based substrate. 15. The method of claim 14, wherein the additive is about 0.0001 wt % to about 50 wt % of the combined weight of the acrylamide pyranose polymer and the additive. 16. The method of claim 14, wherein the additive comprises a buffer, an ionic additive, a surfactant, a colorant, an insecticide, a herbicide, or combinations of any two or more thereof. 17. The method of claim 16, wherein the additive is about 0.0001 wt % to about 50 wt % of the combined weight of the acrylamide pyranose polymer and the additive. 18. A method for at least temporarily retaining moisture in a soil-based substrate, the method comprising applying an acrylamide pyranose polymer to the soil-based substrate; wherein the acrylamide pyranose polymer comprises at least one repeat unit derived from N-(6-deoxy-D-galactose)-acrylamide, N-(6-deoxy-D-galactose)-methacrylamide, N-(1-methyl-6-deoxy-D-glucose)-acrylamide, or N-(1-methyl-6-deoxy-D-glucose)-methacrylamide, and at least one repeat unit derived from N,N-(2,6-deoxy-D-glucose)-2,6-acrylamide.
