liquid agrochemical compositions comprising a polymeric thickener and an alcohol-containing solvent system, and liquid herbicidal compositions having an alcohol-containing solvent system
Patent Summary: "Liquid agrochemical compositions comprising a polymeric thickener and an alcohol-containing solvent system, and liquid herbicidal compositions having an alcohol-containing solvent system". The present invention relates to liquid agrochemical compositions, including a mixture of: agrochemical active ingredients (in particular herbicides)； C1-C6 alkyl methacrylate polymer (in particular isobutyl methacrylate polymer), which acts as a thickener； and solvent system comprising: (c1) alcohol solvent comprising hexylene glycol (2-methyl-2,4-pentanediol), benzyl alcohol, diacetone alcohol (2-methyl-4-oxo-pentane-2-ol), isobutanol , n-pentanol, n-hexanol, n-heptanol, n-octanol, 2-ethylhexanol, cyclohexanol, dipropylene glycol, diethylene glycol monomethyl ether, dipropylene glycol monomethyl ether, ethylene glycol, or a mixture from two or more of these alcohols (preferably hexylene glycol)； and (c2) heavy aromatic hydrocarbon solvent. The invention further provides method for controlling and / or inhibiting weed growth and using C1-C6 alkyl methacrylate polymer as a thickener in agrochemical composition to increase its viscosity.resumo patente de invenção: "composições agroquímicas líquidas compreendendo um espessante polimérico e um sistema solvente contendo álcool, e composições herbicidas líquidas tendo um sistema solvente contendo álcool". a presente invenção refere-se a composições agroquímicas líquidas, dentre as quais, compreende uma mistura de: ingredientes agroquimicamente ativos (em particular herbicidas)； polímero de metacrilato de alquila c1-c6 (em particular polímero de metacrilato de isobutila), o qual atua como espessante； e sistema solvente compreendendo: (c1) solvente de álcool compreendendo hexileno glicol (2-metila-2,4-pentanodiol), álcool de benzila, álcool de diacetona (2-metila-4-oxo-pentano-2-ol), isobutanol, n-pentanol, n-hexanol, n-heptanol, n-octanol, 2-etil-hexanol, ciclo-hexanol, dipropileno glicol, éter de monometila de dietilen
