摘要:
A device treats a thread with compressed air. To this end, the device has an intermingling device which is encapsulated in a housing with respect to the environment. For thread guidance, the housing has a thread inlet and an opposite thread outlet. In order to prevent direct transmission of noise through the thread inlet and the thread outlet, the thread inlet and/or the thread outlet is formed in each case by two separate opening slots in quick succession and a thread guiding member between the opening slots.
摘要:
An aqueous paint formulation having an aqueous basecoat and an aqueous dispersion having an at least partially neutralized ethylene copolymer wax, wherein the ethylene copolymer wax contains as comonomers in copolymerized form (A) 12-40 wt % of an ethylenically unsaturated carboxylic acid of formula (I), (B) 60-88 wt % of ethylene, and (C) 0-10 wt % of a further comonomer; or the ethylene copolymer was contains as comonomers in copolymerized form (A′) 5-50 wt % of a comonomer of formula (II), (B′) 50-95 wt % of ethylene, and (C′) 0-20 wt % of a further comonomer; wherein the ethylene copolymer wax comprising the comonomers (A), (B), and optionally (C) has a molecular weight Mw of 10000 to 150000 g/mol, and the ethylene copolymer wax comprising the comonomers (A′), (B′), and optionally (C′) has a molecular weight Mw of 5000 to 40000 g/mol.
摘要:
A process for producing an absorbent composite by contacting a solid supporting material with an emulsion comprising at least one polymeric material and at least one crosslinker and curing the mixture on the supporting material, the absorbent composites and also their use in sealing materials for road, tunnel and water engineering and also for excavations, high water protection and roof-sealing systems.
摘要:
The present invention relates to a method for the continuous production of a polymer by radical polymerization, wherein at least three materials are mixed with microstructures in one or more mixers and are then polymerized in at least one reaction zone.

摘要:
The invention relates to the use of cationic polycondensation products as additives for fixing colors and/or inhibiting the running of colors, for washing products and washing aftertreatment products. Said cationic polycondensation products can be produced by the condensation of (A1) non-cyclic amines obtained by the reaction of (A1 a) mono(N,N-dialkylaminoalkyl)amines with (A1 b) bifunctional compounds selected from the group containing urea, thiourea, dialkyl carbonates, aliphatic and aromatic dicarboxylic acids, and aliphatic and aromatic diisocyanates, in a molar ratio 1.2:1 to 2.1:1, or (A2) mixtures of non-cyclic amines (A1) and cyclic amines (A3) in a molar ratio 10:1 to 1:10 with (B) bifunctional compounds selected from the group containing alkylene dihalogenides, dihalogen alkyl ethers, halomethyl oxiranes, and bisepoxides, in a molar ratio (B) to (A1) or (B) to (A2) from 0.6:1 to 1.3:1.
摘要:
A process for preparing aqueous solutions of homo- or copolymers of acrylic acid with a mean molar mass Mn of from 500 g/mol to 10 000 g/mol by means of controlled free-radical polymerization in an aqueous medium.
