    Abstract: A process for the purification of organic sulfur compounds involves bringing the organic sulfur compounds, in a liquid phase, into contact with an oxide of a metal from groups VIIb or VIIIb and an oxide of a metal from groups Ia to IIIa of the periodic system, or alternatively, with a mixed-oxide thereof; for a contact period of at least 1 minute. Afterwards, the oxides and the organic sulfur compounds are separated.

    Abstract: A block copolymer contains at least a block (P1) and a block (P2). The block (P1) is obtained or obtainable by reaction of a triblock copolymer having the structure A-B-A′, where block B is selected from polyethers or polyesters and blocks A and A′ are identical or different, and at least one polymer (PM) selected from polyesters and polyethers. The block (P2) is selected from polyamides and polyesters. A process can be used for producing the inventive block copolymer, a shaped article can be made containing the inventive block copolymer, and the inventive block copolymer can be used for producing a shaped article.
