Abstract: Se describe un metodo para producir espumas polimericas a partir de resinas de policondensacion reactivas con un diametro de poro maximo de 1 (m. Tal metodo comprende las etapas de: 1) producir una mezcla gelable de la resina de policondensacion reactiva en un solvente o agente de dispersion; 2) producir una dispersion acuosa que contiene particulas polimerica; 3) mezclar la mezcla obtenida en la etapa 1) con la dispersion obtenida en la etapa 2), por lo que se obtiene un gel hidratado; y 4) secar el gel hidratado de manera que se obtiene la espuma polimerica. El proceso de secado en la etapa 4) tiene lugar en una presion y temperatura que cae debajo de la presion critica y debajo de la temperatura critica de la fase liquida del gel mientras el gel no se pone en contacto con un liquido organico con el fin de reemplazar el agua contenida en el gel por la siguiente etapa 3) liquida y antes de la etapa 4).

Abstract: Nanoporous polymer foam (I) obtained by expanding a multi-phase, blowing agent-containing polymer mixture (II) with domains in the range of 5-200 nm, in which the solubility of the blowing agent (III) in the domain-forming phase is at least twice as high as in the adjacent phases. Independent claims are also included for (1) a method for the production of (I) by making a multi-phase mixture (II) as above, impregnating the mixture with (III) and expanding the mixture (2) expandable mixtures (II) as above .

Abstract: Tert.-dodecylmercaptan (I), obtained by the acid-catalysed addition of hydrogen sulfide to a mixture containing olefins derived from n-dodecane, 5-methyl-n-undecane, 4-ethyl-n-decane, 5,6-dimethyl-n-decane, 5-ethyl-6-methyl-n-nonane, 4,5-diethyl-n-octane and other hydrocarbons, in amounts of 10-18, 25-40, 25-40, 2-8, 5-12, 1-5 and up to 5 wt% respectively. Independent claims are also included for (1) a method (M1) as described above for the production of (I) (2) a method (M2) for the regulation of mol. wt. in the polymerisation of vinyl monomers by adding (I) as mol. wt. regulator.

Abstract: The invention relates to a method for producing an aqueous styrene-butadiene polymer dispersion by means of radical aqueous emulsion polymerisation of a monomer mixture M containing styrene, butadiene, and optionally up to 30 wt. %, in relation to 100 wt. % of monomers, of ethylenically unsaturated comonomers other than styrene and butadiene. The reaction is carried out in a polymerisation vessel according to a monomer supply method, in the presence of a regulator system comprising, in relation to 100 wt. % of monomers, between 0.02 and 0.5 wt. % of at least one hydrocarbon KW having between 6 and 20 C atoms and being selected from compounds forming a pentadienyl radical or a 1-phenylallyl radical by means of abstraction of a hydrocarbon atom, an alpha -methylstyrene dimer, and between 0.3 and 2 wt. % of an organic compound S with at least one SH group. The inventive method is characterised in that at least 30 %, preferably at least 50 %, especially at least 80 %, and ideally the entire amount (or more than 95 %) of the hydrocarbon KW is present in the polymerisation vessel.
