Abstract: A process is disclosed for preparing products from the reaction of polyasparaginic acid imides with aminoacids by reacting aminoacids with polyasparaginic acid imides in an aqueous medium at pH values at which at least 5% of the amino groups of the aminoacids having a non-protonated form are in equilibrium with those having a protonated form. Also disclosed is the use of the thus obtained reaction products and of products from the reaction of polyasparaginic acid imides with alkanolamines or aminated C1-C30-fatty alcohol alkoxilates which contain up to 50% by moles of polymerized ethylene and/or propylene oxide per mole of fatty alcohol. These products are useful as additives for washing and cleaning agents, as scale inhibitors and as dispersing agents.

Abstract: Production of rubber-modified styrene polymers (I) comprises (1) producing rubber (II) dispersion by anionic dispersion polymerization of diene and optionally styrene monomer(s) in 3-6 carbon aliphatic hydrocarbon (III) which is nonsolvent for (II); (2) mixing intensively with styrene monomer and optionally comonomer, without separating (III), to dissolve (II) in monomer(s); and (3) anionic or free radical polymerization of (II) solution to (I) and simultaneous removal of (III). An independent claim is also included for rubber-modified styrene polymers made by this process.

Abstract: In a process for polymerizing dienes in a solvent comprising vinylaromatic monomers, the polymerization is carried out in the presence of a metal compound of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo or W as catalyst and a Lewis acid as cocatalyst and, if desired, an alkylating agent and, if desired, a regulator. This process can be used for preparing high-impact polystyrene, acrylonitrile-butadiene-styrene copolymers or methyl methacrylate-butadiene-styrene copolymers.
