A method of identifying different plastics, wherein each plastic is provided with a plurality of fluorescent dyes which differ in terms of their emission frequencies and/or in terms of the duration of their fluorescence, so that a fluorescence pattern, which is distinguished by the duration of the fluorescence and/or by the frequencies occurring, can unambiguously be assigned to each plastic.

Method for the identification of plastics

Multi-block copolymers of recurring structural units of polysiloxanes and recurring structural units of aliphatic polyesters, polyethers or polyetheresters with rubber properties, the individual polymeric blocks constituting rubber-type products with glass transition temperatures below practical usefulness and a process for their production.

New polysiloxane block copolymers

Block copolymers of recurring structural units of the series of polysiloxanes and recurring structural units of the series of aliphatic polyesters, polyethers or polyetheresters with rubber properties, the polymeric block-forming polymers in each case producing rubber-type products with glass transition temperatures below practical temperatures of use and a process for the production thereof.
