Abstract: The concentration of organoaluminum compounds in their solutions can be determined quantitatively, even in a range of less than 10 mmols/dm3, when adding to the solution to be analyzed instantaneously an excess of reactant and when measuring the produced reaction heat.

Abstract: Copolymers of ethylene and higher 1-olefins which are suitable for the manufacture of thin films, are preferably prepared in a two-step process, the first step yielding a polymer having a high molecular weight, the second step giving a polymer having a low molecular weight. The films obtained from these copolymers have improved mechanical properties as compared to films manufactured from known corresponding raw materials. The mechanical properties are furthermore uniform in longitudinal and in transverse direction.

Abstract: A Ubbelohde viscosimeter is disclosed which is modified according to the present invention by mounting to its reservoir a pressure tube and to the upper ends of the pressure tube and the conventional capillary tube a double three way cock. The cock controls pressure supply to the reservoir, as well as selectively connecting the reservoir to atmosphere. In addition a separate suction tube is provided in association with the reservoir to permit selective withdrawal of material from the reservoir. By this arrangement viscosity measurements of polymer solutions at high temperatures are possible without removing the viscosimeter from the thermostat for cleaning.
