Also claimed are: (i) a process for the prodn. of the materials, by reacting components (a)-(c) together at 180-280 deg C and 1-100 bar for a mean residence time of 0.2-10 minutes; and(ii) film, fibres and mouldings made from the materials.

    Abstract: A process for the preparation of free-radical-crosslinkable copolymers by polymer-analogous reaction of A) a copolymer (A) comprising a1) from 20 to 85 mol % of a monomer (a1) containing the methacrylic acid structural unit and a2) from 15 to 80 mol % of another free-radical-polymerising monomer (a2), where a3) from 5 to 50 mol % of the total amount of the monomers (a1) and (a2) are monomers (a3) carrying functional groups which are capable of a condensation or addition reaction, with B) an olefinically unsaturated monomer (B) carrying a functional group which is complementary to that of the monomers (a3), characterised in that the polymer-analogous reaction is carried out at from 90 to 150 DEG C and at a mean residence time of from 3 to 20 minutes in highly concentrated solution or in bulk. The free-radical-crosslinkable copolymers which can be prepared by this process are used as binders for powder coatings (paints).

    Abstract: Rubber-modified, high-impact acrylonitrile/butadiene/styrene (ABS) moulding compositions, as obtained by polymerisation of styrene and acrylonitrile in the presence of a preformed rubber, dissolved in monomeric styrene and acrylonitrile and optionally a solvent, containing, as rubber, a styrene-butadiene block copolymer and at least one further polymer which is compatible with styrene-butadiene block rubber or its polystyrene component and is incompatible with polystyrene-acrylonitrile.

    Abstract: A process for producing thin absorbent planar structures which may be used in hygiene products such as diapers, incontinence products, wound contact materials or sanitary napkins to absorb body fluids, comprises the steps of: A) producing a mixture of an adhesive in dispersion form and a particulate absorbent by fluidizing the components, B) applying the mixture of adhesive and absorbent uniformly to the surface of one side of a first planar backing material, C) one side of a second planar backing material is applied to the mixture of adhesive and absorbent that is present on the surface of one side of the first planar backing material, so producing a sandwichlike intermediate, and D) the sandwichlike intermediate is processed to the end product at a temperature of at least 90° C., a pressure of from 4 to 50 bar, and a pressing time of from 0.5 to 5 min.
