    摘要: Aqueous dispersions of crosslinked emulsion polymers comprising tertiary ester groups, comprising (a) at least 50% by weight of an ester derived from a tertiary alcohol and an ethylenically unsaturated C3 to C5 carboxylic acid, (b) 0.001% to 5.0% by weight of at least one compound having at least two ethylenically unsaturated double bonds, and (c) 0% to 49.999% by weight of at least one other monoethylenically unsaturated compound in interpolymerized form and having an average particle size of not more than 1000 nm, and water-absorbing materials obtainable by coating a backing material with the aqueous dispersion described of crosslinked emulsion polymers comprising tertiary ester groups, drying and heating the thus treated backing material to a temperature of at least 140° C. to form carboxyl groups from the tertiary ester groups of the emulsion polymer and at least partly neutralizing the carboxyl groups, and also the use of the water-absorbing materials as an absorbent for water and aqueous fluids.

    摘要: The invention relates to a solvent-stable metal catalyst having slightly coordinating counter anions of formula I [M(L)a(Z)b]m+m(A−)(I), wherein M represents a transition metal of groups 3-12 of the periodic system, a lanthanide or a metal of groups 2 or 13 of the periodic system; L represents a solvent molecule; Z represents a mono or polycharged ligand; A− represents a slightly or non coordinated anion; a represents a whole number which is greater than or equal to 1; b represents a whole number which is greater than or equal to 1, whereby the total from a and b is between 4 and 8, and m represents a whole number from 1 6. The invention also relates to a method for polymerising olefinically unsaturated compounds in the presence of said catalyst and copolymers which are made of monomers comprising isobutene and at least one vinylaromatic compound which is obtained according to said inventive method.
