Abstract:
Microcápsula que comprende un núcleo a) que contiene una sustancia fragante u odorífera, y una envoltura b), en cuyo caso b) puede obtenerse mediante polimerización de - uno o más ésteres alquílicos de C1-C24 del ácido acrílico y/o metacrílico y - al menos dos monómeros bi- o polifuncionales diferentes.
Abstract:
The present invention is related to a method for the pesticidal treatment of crops which have a final growth height of at least 140 cm, comprising the treatment with an encapsulated pesticide at a growth height of the crop of up to 120 cm. The invention further relates to a composition comprising an encapsulated pesticide and a composition comprising a mixture of an encapsulated pesticide and a non-encapsulated, additional pesticide. Finally, the invention also relates to a use of an encapsulated pesticide for the pesticidal treatment of crop which has a final growth height of at least 140 cm at a growth height of the crop of less than 120 cm.
Abstract:
The present invention relates to microcapsules, comprising a capsule core and a capsule wall, wherein the capsule wall is composed of 50 to 90% by weight of one or more C1-C24-alkyl esters of acrylic and/or methacrylic acid (monomers I), 10 to 50% by weight of one or more polyvinyl monomers (monomers II), and 0 to 30% by weight of one or more monounsaturated, non-ionizable monomers (monomers III), which are different from monomers I, in each case relative to the total weight of the monomers. The invention further relates to a method for the production of said microcapsules, and to the use thereof in binding building materials, textiles and heat transfer fluids.
Abstract:
The invention relates to metal-nanoparticles and to methods for the production thereof in which a metallic salt solution is reduced by means of a reducing agent in the presence of the derivatised polyethylenimines or polyvinylamines. Metal salt solutions of two or more different metals can be reduced at the same time or successively. The metallic nanoparticles are obtained from two or more different metals. Metals are preferably silver, palladium and platinum. Suitable reducing agents are, for example, formic acid, formaldehyde, diethanolamine, 5-pentenic acids and sodium borohydride. Silver can be used in the form of silver oxide and/or silver nitrate, palladium can be used in the form of alkali tetrachloropalladate or palladium(ll)nitrate and platinum can be used in the form of alkali tetrachloroplatinate or tetraamine platinum(ll)nitrate.
