  Anomers and epimers alpha- and beta-gluco and -galactosides are expected to behave differently. However, recent results on a series of Guerbet glycosides have indicated similar liquid crystal clearing temperatures for pure p-glucosides and the corresponding alpha-galactosides. This observation has led to speculation on similarities in the self-assembly interactions between the two systems, attributed to the trans-configuration of the 4-OH group and the hydrophobic aglycon. Previous simulations on related bilayers systems support this hypothesis, by relating this clearing transition temperature to intralayer (sugar-sugar) hydrogen bonding. In order to confirm the hypothesis, the comparison was expanded to include the cis-configurated pair, that is, alpha-gluco/beta-galactoside. A set of alpha-configurated Guerbet glucosides as well as octyl alpha-galactoside were prepared and their thermotropic phase behavior studied. The data obtained enabled a complete comparison of the isomers of interest. While the results in general are in line with a pairing of the stereo-isomers according to the indicated cis/trans-configuration, differences within the pairs can be explained based on the direction of hydrogen bonds from a simple modeling study.

  The present invention relates to an agrochemical composition containing a pesticide and a copolymer, which contains in polymerized form at least 20 wt % vinylimidazol and/or a quaternized vinylimidazol, an acidic comonomer, and a hydrophobic comonomer, which comprises C 1-22 alkyl (meth)acrylate, mono C 1-22 alkyl terminated poly(ethylene glycol) (meth)acrylate, vinyl ester of aliphatic C 1-32 carboxylic acids, or vinyl C 1-4 alkyl ether. It further relates to a method for preparing said composition by mixing the pesticide and the copolymer; and to a use of said copolymer as dispersing agent in a composition containing a pesticide. In addition it relates to 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 said composition 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. Finally, it relates to seed containing the said composition.
