摘要:
The invention relates to the use of aqueous dispersions as auxiliary agents for wastewater treatment, said dispersions containing at least one at least partially neutralised ethylene copolymer wax selected from ethylene copolymer waxes containing (A) between 26.1 and 39 wt. % of at least one ethylenically unsaturated carboxylic acid, and (B) between 61 and 73.9 wt. % of ethylene, as comonomers which have been incorporated by polymerisation, and selected from ethylene copolymer waxes containing (A') between 20.5 and 38.9 wt. % of at least one ethylenically unsaturated carboxylic acid, (B') between 60 and 79.4 wt. % of ethylene, and (C') between 0.1 and 15 wt. % of at least one ethylenically unsaturated carboxylic acid ester, incorporated by polymerisation.
摘要:
Polymer mixtures contain (a) 10 to 90 % by weight of an imide from a copolymer based on an α-olefin and an ethylenically unsaturated dicarboxylic acid and a polyamine; and (b) 10 to 90 % by weight of a copolymer different from (a) which contains at least two monomers from the group formed by ethylene, acryl esters, vinyl esters, vinyl ethers and ethylenically unsaturated dicarboxylic acids or dicarboxylic acid derivatives. Also disclosed is the use of these polymer mixtures as additives for petroleum middle distillates.
摘要:
The invention relates to a method for waterproofing lignocellulosic materials by impregnating the lignocellulosic material with a waterproofing agent, whereby the lignocellulosic material is impregnated with a hardenable aqueous composition before or during waterproofing, said composition containing at least one cross-linkable compound, selected from a) low-molecular weight compounds V, having at least two N-bonded groups of formula CH2OH, wherein R = hydrogen or C1-C4 alkyl, and/or one 1,2-bishydroxyethan-1,2-diyl group, bridging two nitrogen atoms, ß) precondensates of the compound V and Ϝ) reaction products or mixtures of the compound V with at least one alcohol, selected from C1-C6 alkanols, C2-C6 polyols and oligo-C2-C4-alkylene glycols.
摘要:
The invention relates to a method for producing bisphenol alcoxylates, whereby at least one bisphenol is reacted with alkylene oxide in the presence of a phosphine catalyst that contains essentially no alkali hydroxide.

摘要:
The invention relates to a method for producing thixotropic agents containing 0.1 - 30 wt.- % of at least one ethylene terpolymer wax, 5 - 70 wt.- % of at least one solvent, which is incompatible with the ethylene terpolymer wax, and 5 - 85 wt.- % of at least one solvent which is compatible with the ethylene terpolymer wax and or with one or more of the first-named solvents.
摘要:
The invention relates to the use of terpolymers comprising the following as monomer constituents: a) at least one low alkene, b) at least one long-chain alpha olefin, and c) at least one polar polymerisable monomer, as additives for fuel oils and lubricants, and especially as cold flow improvers in fuel oils. The invention also relates to the fuel oils and lubricants to which said terpolymers are added, and to additive packets containing said terpolymers.
