    摘要： The present invention relates to an apparatus for the simultaneous analysis of at least two samples by the field-flow fractionation method, where the apparatus has at least the following elements: a) a source of a defined liquid stream, preferably a pump, b) at least two separation channels, each with at least one inlet and each with at least one outlet for passing the at least two samples through in each case one of the at least two separation channels, c) at least one controllable unit which is connected to the at least two separation channels via their at least one outlet each, and which can pass on the at least two samples, which can be passed through in each case one of the at least two separation channels, separately from one another to at least one unit downstream of the controllable unit.

    摘要： In block copolymers of the general formula A--B--A' which have a molecular weight of less than 300,000 and consist of from 18 to 40% by weight of a vinylaromatic hydrocarbon and from 60 to 82% by weight of one or more partially or completely hydrogenated hydrocarbons and in which A and A' are each a polymer block of a vinylaromatic hydrocarbon and B is a polymer block of a diene hydrocarbon, the weight ratio of the polymer blocks A to A' is less than or equal to 1:5 and greater than 1:10 and the mean molecular weight of polymer block A is from 2,000 to 20,000 and that of the polymer block A' is from 10,000 to 110,000 and the molecular weight of the B block is not less than 18,000. The block copolymers are prepared by a process in which, in a first polymerization stage, the vinylaromatic hydrocarbon is completely polymerized to form the A or A' block, in the second polymerization stage the diene hydrocarbon is completely converted to form the B block and thereafter the second portion of the vinylaromatic hydrocarbon is polymerized on to form the A or A' block, the portion of a vinylaromatic compound for the preparation of the A' block being not less than five times, and not more than 10 times, the weight used to form the A block. The block copolymers are used for the preparation of molding materials.
