Abstract: An improved polymerization and work-up process makes it possible to produce specific nitrile rubbers which have a particular ion index which is responsible for an excellent vulcanization rate and leads to vulcanizates having an advantageous property profile.
Abstract: An improved polymerization and processing method allows the production of special nitrile rubbers which are characterized by a specific cation content which leads to an excellent storage stability and particularly good vulcanization rate and moreover results in vulcanized materials that have advantageous properties.
Abstract: The present invention relates to a method to control a liquid feed stream carried out by measuring at least one spectrum of the liquid feed stream comprising an initiator or catalyst, determining its activity using a predictive model on the basis of said spectrum and adjusting the feed streams and/or the preparation conditions of the feed stream comprising the initiators or catalysts in order to attain or maintain a desired level of total activity.
Abstract: The present invention is directed to a method for preparing isobutene from a renewable source and their use in the preparation of renewable polymers. The invention also discloses purification of isobutene, selective removal of 1-butene, cis-2-butene and trans-2-butene using microporous adsorbent material, and the oligomerization of the purified liquid isobutene yielding diisobutenes and triisobutenes.

Abstract: The invention is directed to an extruder (10), particularly for extruding a synthetic rubber product, which comprises a barrel (24), one or several extruder elements (12, 14), particularly one or several extruder screws and/or a kneader elements (14), arranged inside the barrel (24) for conveying the product, optionally an inlet port for feeding a stripping agent into the barrel (24) and an outlet port for removing volatile compounds from the product and, where applicable, the stripping agent. According to the invention a perforated die plate (26) is fixed to the barrel (24) in flow direction before the outlet port. Since the die plate (26) is not fixed to the extruder elements (12, 14) but to the barrel (24) a circumferential clearance between the die plate (26) and the barrel (24) is prevented so that no extruded material is passing the die plate (26) radially outside.
Abstract: The present invention relates to a high-temperature furnace for T(O)C measurement of a sample, which has a furnace housing which bounds a vaporization space and has a sample opening for the dropwise introduction of the sample and at least one flushing opening for introduction of a flushing liquid. According to the invention, the furnace housing is lined with a spinel ceramic on an inner side facing the vaporization space. By means of the spinel ceramic, the vaporization space is lined with a material which allows particularly high temperatures within the vaporization space and thus very complete combustion and is at the same time very resistant to temperature changes. This allows cleaning with a flushing liquid at essentially the operating temperature of the vaporization space and removal of deposited salts, in particular recrystallized organic salts, from the vaporization space in the flushing liquid in dissolved or undissolved form.
