摘要:
In a motor vehicle having a tail gate (10) affixed to a lateral, rear pillar of the vehicle structure by means of at least one hinge so as to be pivotable about a substantially vertical axis (A-A), a hinge part that swings out together with the tail gate is located in an area of a lateral tail light (18) of the vehicle when the tail gate (10) is closed.

This invention relates to a catalyst system containing bisiminopyridyl complexes of cobalt and/or iron with bulky substituents on the bisiminopyridyl ligand, to a method for the polymerization of &agr;-olefins, particularly ethylene, and to the use of the polyolefins which can be produced by said method for the production of moldings of all types.
摘要:
The present invention relates to a process for the avoidance of instability during the gas polymerization of rubber comprising the feeding of low volatility monomers supported in a particulate material into a fluidized bed reactor.
摘要:
The invention relates to a process for the preparation of supported polymerization catalyst systems comprising the steps of: a) dissolving at least one different transition metal complex in a mixture of at least two different solvents having different boiling points to form a solution, b) contacting said solution with at least one different support material, the volume of the solution being sufficient to form a slurry with the support material, the volume of the higher-boiling solvent being less than or equal to the total pore volume of the support, c) removing more than 90% of the solvent boiling at the lower temperature, and d) adding at least one co-catalyst.
摘要:
The production of diene rubbers polymerized by means of Nd catalysts and having reduced cold flow and low intrinsic odor is effected by the polymerization of diolefines adiabatically at temperatures of -20.degree. to 150.degree. C. in the presence of inert organic solvents and in the presence of metallo-organic mixed catalysts based on neodymium carboxylate, by subsequently depressurizing the reaction mixture obtained in this manner by reducing the pressure, and by treating the reaction mixture thereafter with disulphur dichloride, sulphur dichloride and/or thionyl chloride.

The present invention is directed to a catalyst system, the use thereof in the polymerization of dienes in a solution, suspension and vapor phase, and the use of diene rubbers produced therewith, exhibiting a high cis content, an average vinyl content and a low gel content.
摘要:
The production of impact-resistant polystyrene with EPDM simplifies the process and produces improved products if a modified ethylene/propylene rubber consisting of styrene/butadiene- or diene polymers, ethylene, optionally propylene and an unconjugated diene are used as the elastifying component.The modified EPDM rubbers consisting of (a) from 20 to 90% by weight of ethylene units, (b) from 1 to 25% by weight of units of a butadiene/styrene copolymer containing a quantity of from 10 to 90% by weight of styrene, (c) from 0 to 10% by weight of units of an unconjugated diolefin and (d) C.sub.3 -C.sub.18 .alpha.-monolefin units to make up the difference to 100% by weight, are a further subject of this invention.
