SHAPED BRICK FOR LINING CHAMBERS OF COKE OVENS AND BUILDING PROCESS OF SUCH CHAMBERS

摘要

the invention relates to powder, networked, aqueous liquids and blood absorbent polymers (super absorbent polymers) formed from (a) 55 to 99.9 wt.% polymerisierten unsaturated, polymerisierbaren, su00e4uregruppenenthaltenden monomers, at least 25 mol% neutralized, (b) 0 to 40 wt.% polymerisierten unsaturated, with (a) copolymerisierbaren monomers, (c) 0.1 to 5.0% by weight.-% of a vernetzungsmittels, d) 0 to 30% by weight.-% of a water-soluble polymer, and the units of weight (a) to (d) are related to anhydrous polymer, characterized by 100 tl the teilchenfu00f6rmigen polymer with an aqueous solution of at most 10) of at least 10% phosphoric acid, and (b) 0.05 to 0.3 ti of a verb indung,the at least two carboxylic groups can respond and no alkalisalzbildende group in the molecule contains, and / or (b) 0.05 to 1 tl of a compound which can react with at least two carboxylic groups and a alkalisalzbildende group in the molecule contains mixed and 150 250u00b0c erhit i have been.the erfindungsgemu00e4u00dfen super absorbent polymers exhibit high retentionskapazitu00e4t, high gelstu00e4rke and high absorption capacity under pressure and without the use of an organic solvent and with only a small amount of media for the oberflu00e4chennachbehandlung of powder a polymer can be produced.the invention concerns also the use of such polymerisate in textile structures to absorb body fluids, with...
