Abstract
The present invention teaches modified organosilicone and their use, a preferred of which is as adjuvants for pesticides. The modified organosilicone have siloxane backbones with pendant, terminal or intermediate amine and polyether groups. The modified groups or the siloxane may be functionalized further with alkyl or alkyleneoxide groups.
Claims34
A composition comprising a) a siloxane having separate polyether and amino functional groups thereon and b) a pesticide.
A composition formed by mixing at least two components:
- a) a siloxane having separate terminal or pendant polyether-containing and amino-containing functional groups thereon and
- b) and acid functional component.
A process for treating plants comprising applying to plants a superspreading composition comprising
- (a) an amino polyether siloxane of the formula:
- [O½Me2SiO½]d[O½MeSi(Z)O½]e[O½MeSi(Q)O½]f[O½SiMe2P]g
- where d is 0 to 2;
- e is >0 and <4;
- f≧0 and <4;
- g is 2 if the siloxane is not cyclic or zero if the siloxane is cyclic;
- d+e+f+g≦6;
- Z=CnH2nO(CaH2aO)wR1;
- n=2 to 4;
- a=2-4;
- w=1 to 30;

- Q is B(O)jR2 N(R3)2 or B(O)jR2N+(R3)3;
- B is a divalent bridging group of C1 to C6;
- R2 is a divalent organic group containing 2 to 8 carbons, each optionally OH substituted;
- j is 0 or 1;
- R3 is hydrogen, an amino alkyl of one to four carbons, an alkyl of 2 to 4 carbon atoms which may have hydroxy substitutions thereon, or a polyether of the general structure —(CaH2aO)bR4;
- each a is 2 to 4;
- each b is 2 to 30;
- the R4 groups independently are hydrogen or a hydrocarbon group of 1 to 4 carbons;
- and P is Q or, provided f is not 0, methyl., and
- (b) a pesticide
