摘要:
The invention relates to the use of cationically-modified, particle-shaped, hydrophobic polymers as addition agents in rinsing, care, detergent and cleaning products including rinsing, care, detergent and cleaning products which contain the cationically-modified, particle-shaped, hydrophobic polymers. The surface of said polymers is cationically modified by a coating of polyvalent metallic ions and/or cationic surfactants, and the particle size of said polymers ranges from 10 nm to 100 mu m.

摘要:
Method for producing polymers having isotactic or syndiotactic regions (concisely organized regions) by polymerization of polymerizable compounds (monomers) in the presence of an optically active compound as the complexing agent. The method is characterized in that the optically active compound is present in the form of only one of the enantiomers possible to a degree of 50 % by weight and polymerization is carried out at temperatures below 20 °C and at least 10 % by weight of the monomers are prochiral compounds.

摘要:
Une nouvelle plaque d'impression offset produite par voie électrophotographique comprend un support électroconducteur indéformable (A), au moins une couche photoconductrice (B) et une surface d'impression (C) composée de régions hydrophiles (c1) non imprimantes qui transportent de l'eau et des régions oléophiles (c2) imprimantes, non colorées par du toner et qui transportent des couleurs. La nouvelle plaque d'impression offset peut être produite de manière connue en soi par voie électrophotographique; on utilise à cet effet des toners hydrophiles ou non aisément hydrophilisables par voie chimique, lorsque l'on les mélange avec des réactifs appropriés, par voie thermochimique, lorsque l'on les chauffe et/ou par voie photochimique ou radiochimique, lorsque l'on les soumet à une irradiation par des rayonnements électromagnétiques ou de particules.
摘要:
The invention relates to methods for improving the colour brilliance and the stability of a colour polymer system consisting of a matrix and discrete polymer particles distributed in the matrix according to a defined space lattice structure. Said method is characterised in that a transparent polymer layer is applied to the colour polymer layer.

The invention relates to a method for improving the colour brilliance and the stability of a colour polymer system which consists of a matrix and discrete polymer particles distributed in the matrix according to a defined space lattice structure, and is obtained by filming an emulsion polymer having a core/shell structure. The inventive method is characterised in that the emulsion polymer can be obtained by polymerisation of monomers in at least one first step (monomers of the core), further polymerisation of monomers in at least one other, second step (transition step), and final polymerisation of monomers in a third step (monomers of the shell). In relation to the percentual composition of the monomer mixture of the three steps, a maximum 30 wt. % of the monomers of the first step correspond to those of the third step and at least 5 wt. % of the monomers of the second step respectively correspond to those of the first and the third step. A maximum 60 wt. % of the monomers of the second step are monomers from either the first or the third step.
