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: Production of homo- or co-polymers from styrene and/or diene monomers by anionic polymerization followed by degassing and addition of a mineral oil additive is such that at least a part of the mineral oil is first added after the degassing step.

Abstract: The continuous process for preparing a polyamide by reacting at least one aminonitrile with water comprises:(1) reacting at least one aminonitrile with water in the presence of an organic liquid diluent at from 90 to 400° C. and from 0.1 to 35x10 Pa in a flow tube containing a Brönsted acid catalyst selected from a beta-zeolite catalyst, a sheet-silicate catalyst or a titanium dioxide catalyst comprising from 70 to 100% by weight of anatase and from 0 to 30% by weight of rutile and in which up to 40% by weight of the titanium dioxide may be replaced by tungsten oxide, to obtain a reaction mixture,(2) further reacting the reaction mixture at from 150 to 400° C. and a pressure which is lower than the pressure in stage 1 in the presence of a Brönsted acid catalyst selected from a beta-zeolite catalyst, a sheet-silicate catalyst or a titanium dioxide catalyst comprising from 70 to 100% by weight of anatase and from 0 to 30% by weight of rutile and in which up to 40% by weight of the titanium dioxide may be replaced by tungsten oxide, the temperature and pressure being selected so as to obtain a first gas phase and a first liquid phase or a first solid phase or a mixture of first solid and first liquid phases and so that the first gas phase is separated from the first liquid phase or first solid phase or from the mixture of first liquid and first solid phases, and(3) admixing the first liquid or the first solid phase or the mixture of first liquid and first solid phases with a gaseous or liquid phase comprising water at from 150 to 370° C. and from 0.1 to 30x10 Pa, to obtain a product mixture.
