    Abstract: L’invention concerne une âme absorbante et un article absorbant, respectivement, dotés de propriétés améliorées, spécialement une performance de réhumidification. L’âme absorbante (80) comprend au moins deux couches (91) (92), chaque couche comprenant de 0 à 10 % en poids de matériau fibreux et de 90 à 100 % en poids de particules polymères absorbant l’eau, sur la base de la somme de particules polymères absorbant l’eau et de matériau fibreux. Dans laquelle les particules polymères absorbant l’eau réticulées en surface au sein de la couche supérieure (91) ont une sphéricité d’au moins 0,89 et l’âme absorbante (80) présente un rapport CRCap/TACap d’au moins 0,65.

    Abstract: Trimethylolpropane esters are new. Trimethylolpropane esters are of formula (1). (1) AO : OCH2CH2, OCH2CH(CH3), OCH(CH3)CH2, n1-n3 : 4-6; n1+n2+n3+n4 : 14-16; m1-m3 : 1-3; m1+m2+m3 : 4-6; R1-R3 : 4-6 Independent claims are included for: (1) a process for the production of esters of formula (1) by reaction of alkoxylated trimethylolpropane with (meth)acrylic acid in the presence of at least one esterification catalyst (C) and at least one polymerization inhibitor (D) as well as optionally a solvent (E) that forms an azeotrope with water; optionally removal of at least a portion of the water from the reaction mixture during or after the water from the reaction, optiionally neutralizing the reaction mixture; optionally removing the solvent if present by distillation and/or stripping with an inert gas; (2) across-linked hydrogel prepared by polymerization of an ester of formula (1) with (meth)acrylic acid with optionally additional monoethylenicaly unsaturated compounds (N) as well as optionally at least a further copolymerizable hydrophilic monomer (M) in the presence of at least one radicatl initiator (K) and optionally a graft base (L); optionally cross-linking of the resulting reaction mixture; drying of the reaction mixture and optionally grinding the reaction mixture; (3) a mixture comprising 0.1-40 wt.% of a ester of formula (1) and (meth)acrylic acid, 0.5-99.9 wt.% of a hydrophilic monomer (M), 0-10 wt.% of an esterification catalyst (C), 0-5 wt.% polymerization inhibitor (D) and 0-10 wt.% sovlent (E).

    Abstract: A process for the post crosslinking of water absorbing polymers comprises treatment with a bicyclic amideacetal crosslinking agent with simultaneous or subsequent heating. A process for the post crosslinking of water absorbing polymers comprises treatment with a bicyclic amideacetal crosslinking agent (I) of formula (I) with simultaneous or subsequent heating. [Image] R 1>-R 9>H, 1-12 C alkyl, 2-12 C alkenyl or 6-12 C aryl, all optionally halogenated An independent claim is included for the resulting water absorbing polymer.
