    Abstract: The invention relates to a process for preparing an impact-modified plastic based on crosslinked rubber particles, where (a) an aqueous dispersion or suspension of particles of a crosslinked rubber is produced from a first monomer mixture which has less than 50% by weight, preferably less than 5% by weight, in particular less than 2% by weight, content of conjugated diene compounds; (b) where appropriate, the dispersion or suspension is precipitated, giving an aqueous rubber particle mixture with water content of at least 5% by weight; (c) the dispersion or suspension of the rubber particles or the aqueous rubber particle mixture is added to a second mixture which comprises at least one other monomer, and (d) the monomers of the second mixture are polymerized. The invention further relates to a plastic obtainable by the process.

    Abstract: A thermoplastic molding composition having little intrinsic color is produced from a graft copolymer and a thermoplastic polymer. The graft copolymer is produced from a soft elastomeric particulate graft base obtained by polymerization of a conjugated diene alone or with a small amount of a monoethylenically unsaturated monomer, upon which is grafted a vinylaromatic monomer and acrylonitrile and optionally another monoethylenically unsaturated monomer. The thermoplastic polymer is a copolymer of a vinylaromatic monomer and acrylonitrile and optionally an additional monoethylenically unsaturated monomer. The thermoplastic molding composition has a low level of intrinsic color coupled with good mechanical properties and can be processed by, for example, extrusion, injection molding, calendaring, blow molding, compression molding, or sintering.

    Abstract: PCT No. PCT/EP97/03397 Sec. 371 Date Oct. 28, 1998 Sec. 102(e) Date Oct. 28, 1998 PCT Filed Jun. 30, 1997 PCT Pub. No. WO98/02466 PCT Pub. Date Jan. 22, 1998A process for preparing an aqueous polymer dispersion by free-radically initiated polymerization of free-radically polymerizable compounds I with moderate solubility in water, whose disperse polymer particles contain not only compounds I but also compounds II with a very low solubility in water where a mixture consisting of a portion of the compounds I and consisting of the compounds II is used to produce an aqueous emulsion I with a droplet size /=1000 nm.
