    • The present invention teaches silicone polyether copolymers with a low degree of polymerization (3 to 4 Si units) provide control for foams generated by organosilicone based surfactants in water without the need for an additional antifoam component. The copolymer foam control agent is a compound of the formula(CH.sub.3).sub.3 SiO[SiO(CH.sub.3).sub.2 ].sub.X [SiOCH.sub.3 R.sup.1 ].sub.Y Si(CH.sub.3).sub.3wherein X+Y=1 to 2, Y.gtoreq.1, R.sup.1 is an alkyleneoxide group of the formula C.sub.a H.sub.2a O(C.sub.3 H.sub.6 O).sub.z R.sup.2 wherein a=3 to 4, z is 1 to 15, R.sup.2 is hydrogen, a hydrocarbon radical of 1 to 4 carbons or acetyl. This invention provides compositions for use in agricultural formulations that give improved foam control for foams generated from organosilicone surfactants in aqueous systems. The copolymer foam control agent is soluble in a surfactant matrix comprised of an organosilicone surfactant alone or in mixtures with short chain conventional surfactants. This invention provides clear, homogeneous, low foaming agricultural formulations having of a water insoluble copolymer foam control agent, and a water soluble or dispersible trisiloxane or tetrasiloxane alkoxylates when said formulation is used in an aqueous mixture.
    • 本发明教导具有低聚合度(3至4个Si单元)的聚硅氧烷聚醚共聚物可提供对在有机硅基表面活性剂在水中产生的泡沫的控制,而不需要额外的消泡剂组分。 共聚物泡沫控制剂是式(CH3)3SiO [SiO(CH3)2] X [SiOCH3R1] YSi(CH3)3的化合物,其中X + Y = 1〜2,Y> = 1,R1为环氧烷基 式(Ⅳ)化合物其中a = 3〜4,z为1〜15,R 2为氢,碳原子数为1〜4的烃基或乙酰基。 本发明提供了用于农用制剂的组合物,其为在水性体系中由有机硅氧烷表面活性剂产生的泡沫提供改进的泡沫控制。 共聚物泡沫控制剂可溶于单体有机硅氧烷表面活性剂或与短链常规表面活性剂混合的表面活性剂基质。 本发明提供具有水不溶性共聚物泡沫控制剂和当所述制剂用于含水混合物时的水溶性或分散性三硅氧烷或四硅氧烷烷氧基化物的澄清均匀的低发泡农业制剂。
