摘要:
A paper size which comprises a stable aqueous dispersion of a reactive size, from 5 to 100% by weight, based on the reactive size, of a substantially linear nitrogen-comprising polymer having at least 3 mmol/g of basic nitrogen atoms, and from 1 to 50% by weight of cationic starch having a degree of substitution of at least 0.05 is described. The paper size has a good sizing effect and a stable viscosity.

Novel dye salts of anionic dyes of the general formula I ##STR1## where F is a radical of an anionic dye, n is 1, 2, 3 or 4, and B.sup.1 and B.sup.2 independently of one another are each unsubstituted or substituted branched alkyl or alkyl-substituted cycloalkyl having a total of 10 to 36 carbon atoms, are very useful for dyeing solvents, printing inks or polymeric film-forming materials.
摘要:
The present invention relates to a process for producing a nanocomposite material from a) at least one inorganic or organometallic metal phase; and b) an organic polymer phase; comprising the polymerization of at least one monomer M which have at least one first polymerizable monomer unit A which has a metal or semimetal M, and at least one second polymerizable organic monomer unit B which is joined to the polymerizable unit A via a covalent chemical bond, under polymerization conditions under which both the polymerizable monomer unit A and the polymerizable unit B polymerize with breakage of the bond between A and B, the monomers M to be polymerized comprising a first monomer M1 and at least one second monomer M2 which differs at least in one of the monomer units A and B from the monomer M1 (embodiment 1), or the monomers to be polymerized comprising, as well as the at least one monomer M, at least one further monomer other than the monomers M, i.e. a conventional monomer which does not have a monomer unit A and is copolymerizable with the monomer unit B (embodiment 2).
摘要:
A subject matter of the present invention is a process for the preparation of effect compound-comprising microparticles M comprising A) the formation of a crude suspension of microparticles A by means of enzymatic polyester synthesis in an inverse miniemulsion comprising enzyme, effect compound and polyester monomers; and B) the polymerization of wall monomers from the group consisting of ethylenically unsaturated monomers, polyisocyanates and polyepoxides in the crude suspension of microparticles A. Furthermore, the present invention relates to microparticles M which can be obtained by means of the process according to the invention and also to an agrochemical formulation comprising microparticles M. In addition, the present invention relates to the use of microparticles M prepared according to the invention as component in colorants, cosmetics, drugs, biocides, plant protection agents, fertilizers, additives for food or animal fodder, or auxiliaries for polymers, paper, textiles, leather, detergents or cleaners. Finally, the invention also relates to a method for combating undesirable plant growth, to a method for combating undesirable insect or acarid infestation on plants and/or for combating phytopathogenic fungi, and to seeds treated with the agrochemical formulation.
摘要:
Solid mixtures of a reactive size and starch, which are obtainable by mixing at least one reactive size with at least one starch in a melt in the presence of at least one destructuring agent for starch under the action of shear forces at from 65 to 250° C. and cooling the melt to room temperature, are used in the form of aqueous dispersions as process assistants in papermaking.
