Abstract

The present invention provides multifunctional amphiphilic copolymers having the structure set out below: wherein w, x, y, and z are molar percentages, the sum of which equals 100%; wherein R 1 has the formula —(CH 2 CH 2 O) n —R 2 , where R 2 is hydrogen or a C 1 -C 10 alkyl group; R 3 has the formula —(CH 2 ) a —CH 3 ; R 4 is hydrogen or methyl; R 5 has the formula —(OCH 2 CH 2 ) b —O—(CH 2 ) c —CH 3 or —(OCH 2 CH 2 ) b —O—C 6 H 5 ; and n is an integer ranging from 1 to about 10, a is an integer ranging from 1 to about 21, b is an integer ranging from 1 to about 23, and c is an integer ranging from 1 to about 21. The present invention also provides compositions comprising the multifunctional amphiphilic copolymers including spray drift control compositions including agricultural compositions, consumer compositions, industrial compositions, and mining compositions. The present invention also provides methods for preparing and using the multifunctional amphiphilic copolymers.

Claims (15)

1. A multifunctional amphiphilic copolymer having the following structure:

wherein w is about 10%, x is about 30%, y is about 30%, z is about 30%, and n is from 2 to 8, wherein w, x, y, and z are molar percentages, the sum of which equal 100%.

2. A spray drift control composition comprising a multifunctional amphiphilic copolymer having the following structure:

wherein w is about 10%, x is about 30%, y is about 30%, z is about 30%, and n is from 2 to 8, wherein w, x, y, and z are molar percentages, the sum of which equal 100%.

3. The composition according to claim 2 , wherein the spray drift control composition is selected from the group consisting of agricultural compositions, consumer compositions, industrial compositions, and mining compositions.

4. The composition according to claim 2 , further comprising a crop oil, seed oil, proprietary oil blend, or mixtures thereof; an effective amount of an agricultural agent; and water in a quantity sufficient to reach final volume.

5. The composition according to claim 4 , wherein the composition is an agricultural spray drift composition.

6. The composition according to claim 5 , wherein the agricultural agent is an herbicide, pesticide, fungicide, or mixtures thereof.

7. A method for improving the health of plants comprising contacting a plant with a composition comprising:

(a) a multifunctional amphiphilic copolymer having the following structure:

wherein w is about 10%, x is about 30%, y is about 30%, z is about 30%, and n is from 2 to 8, wherein w, x, y, and z are molar percentages, the sum of which equal 100%;

(b) a crop oil, seed oil, proprietary oil blend, or mixtures thereof;

(c) an effective amount of an agricultural agent; and

(d) water in a quantity sufficient to reach final volume.

8. The method according to claim 7 , wherein the agricultural agent is an herbicide, pesticide, fungicide, or mixtures thereof.
