Abstract: The invention relates to a device and a process for recovering polymer from a melt or solution containing volatile components. The device consists of an evaporating zone passing, via a metering device, which can function also as a pressure-reducing device, into a devolatilizing extruder. The metering and pressure-reducing device makes it possible also to process highly viscous melts of high-molecular polymers and to fill the extruder screws incompletely so that substantial devolatilization is realized in the extruder.

Abstract: A process for the preparation of methyl tertiary butyl ether (MTBE) in two stages:the first stage comprising the reaction of isobutene with methanol in the presence of an acid catalyst, yielding MTBE, while the second stage comprises firstly the conversion of normal-butenes present in the hydrocarbon flow, which remains behind after separation of the MTBE formed in the first stage into isobutene and secondly passing the mixture thus obtained to a reaction zone to form MTBE.Optionally an extra amount of methanol can be supplied to said reaction zone. Said reaction zone can be the same as that used in the same first stage or another one.

An improved supported chromium-containing catalyst is prepared by reacting (1) a chromium chelate of a 1,3-diketo compound and (2) a vanadium chelate or a vanadyl chelate of a 1,3-diketo compound, separately or jointly with (3) an organometallic compound of an element from Group II or III of the periodic system, jointly contacting the resulting reaction products of (1) and (2) with (3) with an inert inorganic supporting material so as to deposit such reaction products thereon, whereafter the supporting material containing the reaction products is heated in a non-reducing atmosphere at a temperature of between 200.degree. and 1200.degree. C. The 1,3-diketo compounds of (1) and (2) are the same or different, and have the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different, R.sub.1 and R.sub.3 being an alkyl group of 1-10 carbon atoms, and R.sub.2 being selected from the group consisting of an alkyl group with 1-10 carbon atoms, and a hydrogen atom.
