    Abstract: Isobutylene polymers are prepared continuously, in aliphatic C3-C6-hydrocarbons in the presence of soluble cationic polymerization initiators and coinitiators at from -40 DEG to 40 DEG C. and under from 0.01 to 10 bar, and the solvents and monomers vaporized during the polymerization are recycled, by a process in which the liquid stream of the monomer solution, containing 40-95, in particular 50-85, percent by weight of the monomers, the liquid streams of the recycle and of the coinitiator solution and the separate stream of the initiator solution are combined in a first zone containing the polymerization zone, and the resulting polymer solution is taken off continuously through a second zone vertically below the first zone. The liquid streams of the monomer solution, the coinitiator solution and the recycle can furthermore be fed into the first zone separately from one another.

    Abstract: Copolymers of 4-methylpentene-1 are prepared by copolymerization of 4-methylpentene-1 with one or more other C2-18 alpha -alkenes at a temperature above room temperature and in the presence of hydrogen using a Ziegler/Natta catalyst system. The polymerization is carried out at a relatively very high temperature and in the presence of an inert gas with the proviso that the partial pressures of the inert gas and of the hydrogen and the sum of the partial pressures of the inert gas, hydrogen and 4-methylpentene-1 have specific values. In this way, copolymers having large crystalline fractions are obtained in a high yield per unit of catalyst system per unit time.

    Abstract: Polymers of 4-methylpentene-1 alone or with up to 10 wt. % of other 2-18C -alpha-mono-olefines as comonomer, are obtd. by polymsn. at 90-150 degrees in the presence of hydrogen at a partial pressure of 0.1 to 10.00 atm., and using a Ziegler-Natta catalyst system comprising (a) a TiCl3 component and (b) an alkylaluminium component, the atomic ratio of Ti:Al in the system amtg. to from 1:1 to 1:100. By use of temp. of 90-150 degrees C, which is higher than used in the otherwise comparable known process, a higher yield per unit catalyst and per unit time is obtD. without deleterious effects on product crystallinity. The polymers are valuable for making transparent moulded or injection moulded articles which are heat resistant to 150 degrees C.

    Abstract: Process for the continuous production of electrically conductive homopolymers and copolymers of compounds from the class of the 5-member heterocyclic compounds containing a conjugated pi -electron system, which contain nitrogen, oxygen or sulphur as the heteroatom, these compounds or mixtures of these compounds being anodically oxidised in electrolyte solvents in the presence of supporting electrolytes, the polymer being deposited on the anode surface and the anodes being formed as hollow bodies or profiled bodies.
