Abstract

A composition and a method of preparing the composition are provided herein. The composition comprises an active substance and a polymeric additive comprising at least one unit represented by the formula (I):

wherein each R is independently selected from the group of a hydrogen atom, an alkyl group, an aryl group, and combinations thereof; and Z comprises at least 10 units represented by the formula (II):

wherein each R 1 is independently selected from the group of a hydrogen atom, an alkyl group, an aryl group, a carbonyl group, a hydroxyl group, an ether group, and combinations thereof and R 2 is a C 1 -C 10 hydrocarbon group. The polymeric additive further comprising at least one unit represented by the formula (III):

A   (III)

wherein A is an alkyleneoxy group having from 2 to 10 carbon atoms.

First claim

What is claimed is:

1. A composition comprising:
a pesticide; and
a non-crosslinked polymeric additive comprising:
1) at least one unit represented by the formula (I):

wherein each R is independently selected from the group of a hydrogen atom, a C1 to C5 alkyl group, and combinations thereof; and Z comprises a group according to formula (II):

wherein n is an integer ≧10;
wherein each R 1 is independently selected from the group of a hydrogen atom, an alkyl group, and combinations thereof; and R 2 is a C 1 -C 10 hydrocarbon group; and
2) at least one unit represented by the formula (III):
A   (III)

wherein A is an alkyleneoxy group having from 2 to 10 carbon atoms;
wherein the composition is an aqueous suspension and pesticide is present in form of solid particles which are suspended in said aqueous suspension.

2. The composition as set forth in claim 1 wherein said group represented by the formula (II) is present in said polymeric additive in an amount of from 45% to 75% by weight based on the total weight of said polymeric additive.

3. The composition as set forth in claim 1 , wherein said polymeric additive has a number average molecular weight of from 5,000 to 200,000 g/mol.

4. The composition as set forth in claim 1 wherein each R is independently selected from the group of a hydrogen atom, a methyl group, or combinations thereof, and A is an alkyleneoxy group having from 2 to 3 carbon atoms.

5. The composition as set forth in claim 1 wherein R 1 is a hydrogen atom.

6. The composition as set forth in claim 1 wherein R 2 is a methyl group.

7. The composition as set forth in claim 1 wherein said polymeric additive is present in an amount of at least 0.5 percent by weight based on the total weight of said composition.

8. The composition as set forth in claim 1 wherein said polymeric additive is present in an amount of at least 5 percent by weight based on the total weight of said composition.

9. A method of preparing a composition as defined in claim 1 comprising the step of combining the pesticide and the polymeric additive to form the composition.

10. The method as set forth in claim 9 further comprising the step of combining a grinding media with at least one of the pesticide and/or the polymeric additive when the pesticide is in solid particle form.

11. A method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants, where the composition as defined in claim 1 is allowed to act on the particular pests, their habitat or the plants to be protected from the particular pest, the soil and/or on undesired plants and/or the useful plants and/or their habitat.

12. The method of claim 11 , wherein said polymeric additive has a number average molecular weight of from 5,000 to 200,000 g/mol.

13. The method of claim 11 , wherein each R is independently selected from the group of a hydrogen atom, a methyl group, or combinations thereof, and A is an alkyleneoxy group having from 2 to 3 carbon atoms.

14. The method of claim 11 , wherein R 1 is a hydrogen atom.

15. The method of claim 11 , wherein R 2 is a methyl group.

16. A method of enhancing the pesticidal activity of a pesticide comprising combining the pesticide with a non-crosslinked polymeric additive;
wherein said polymeric additive comprises:
1) at least one unit represented by the formula (I):

wherein each R is independently selected from the group of a hydrogen atom, a C1 to C5 alkyl group, and combinations thereof; and Z comprises a group according to formula (II):

wherein n is an integer ≧10

2) at least one unit represented by the formula (III):
A   (III)

wherein A is an alkyleneoxy group having from 2 to 10 carbon atoms;
wherein the pesticide is present in form of solid particles which are suspended in an aqueous suspension.

17. The method as set forth in claim 12 , wherein the amount of the polymeric additive is in the range of from 10 to 500 wt %, based on the weight of the pesticide.

18. The method of claim 17 , wherein the polymeric additive comprises:
1) at least one unit represented by the formula (I):

wherein each R is independently selected from the group of a hydrogen atom, a C1 to C5 alkyl group, and combinations thereof; and Z comprises a group according to formula (II):

wherein n is an integer ≧10
wherein each R 1 is independently selected from the group of a hydrogen atom, an alkyl group, and combinations thereof; and R 2 is a C 1 -C 10 hydrocarbon group; and
2) at least one unit represented by the formula (III):
