摘要:
A fluidized-bed process for preparing hydrogen peroxide, C.sub.1 -C.sub.4 -monopercarboxylic acids and C.sub.4 -C.sub.18 -dipercarboxylic acid complexes in which a solution of hydrogen peroxide, a C.sub.1 -C.sub.4 -monopercarboxylic acid, a C.sub.4 -C.sub.18 -dipercarboxylic acid or a mixture thereof in water or carboxylic acids is applied to a pulverulent or pregranulated matrix and fluidized-bed drying takes place.
摘要:
Iodophore containing a) 20-71% by weight of PVP or poly-N-vinylcaprolactam, b) 20-71% by weight of dextrin of DE 2-40, c) 6-25% by weight of elemental iodine, d) 3-12.5% by weight of iodide ions, and process for its preparation are disclosed.
摘要:
Copolymers are prepared from monoethylenically unsaturated monomers containing acid groups and N-vinyllactams and, if required, other monoethylenically unsaturated monomers by copolymerization of monomers in the presence of free radical polymerization initiators by a solution polymerization method in water at a pH of at least 6, by a process in which an alkali metal base or an alkaline earth metal base or a mixture thereof is used for establishing the pH of the aqueous reaction solution.
摘要:
Carboxyl-containing polycondensation products having glass transition temperatures T.sub.G .gtoreq.20.degree. C. obtained from anhydrides of tricarboxylic or tetracarboxylic acids and diols, diamines or amino alcohols are used for cosmetic purposes, in particular as hair treatment compositions.
摘要:
A curable thickened polyester resin molding compound contains from 0.1 to 20 parts by weight of a thermoplastic vinyl polymer which is compatible with the resin and contains acid groups.
摘要:
A crop protection agent containing an active ingredient and based on a polymeric carrier, the active ingredient being adsorbed onto, dissolved in or otherwise bound to the said carrier, contains, as the polymeric carrier, a macroporous crosslinked, preferably styrene-containing, polymer having a particle size such that the said agent can be distributed by means of a conventional apparatus for applying crop protection agents, the active ingredient being taken up in the carrier by absorption.
摘要:
Copolymers of monoalkyl maleates or maleic acid and salts thereof and vinyl alkyl ethers are prepared by free radical copolymerization of maleic anhydride and vinyl alkyl ethers and subsequent reaction with an alkanol or water and optionally metal hydroxides and/or oxides in a process wherein at every stage of the polymerization the vinyl alkyl ether component is present in excess in the reaction mixture, the free radical copolymerization is carried out in acetone and the acetone is removed by distillation during or after the esterification or hydrolysis, which comprises using a peroxyester of a carboxylic acid of 8 or more carbon atoms as polymerization initiator. The copolymers obtained are used in cosmetic preparations.
摘要:
