Abstract: A process stabilizes polyisobutenes by processing the polyisobutenes in at least one kneader or extruder. The polyisobutene contains at least one chromanol as a stabilizer, or the chromanol is incorporated into the polyisobutene. The polyisobutene is added to or forms sealants, adhesives, coatings, roofings, white and black filled sheeting, and chewing gum.

Abstract: Various polyisobutene derivatives are useful as additives in rubbers, particularly for dispersion and compatibilization of additives in rubbers for vehicle tires, such as carbon black, zinc oxide, and silicates.

Abstract: The present invention relates to a semiconductor structure and a method for its production, the semiconductor structure comprising at least one conductor region and at least two semiconductor regions, which semiconductor regions are partly separated by the at least one conductor region. The at least one conductor region comprises openings extending between the semiconductor regions which are partly separated by the respective conductor region. The semiconductor regions comprise at least one organic semiconductor material having a specific HOMO energy level, in particular a DPP polymer. The conductor region comprises a conductive material having a specific work function, said combination of specific energy level and work function allowing for a simple preparation of the conductive region. The invention further relates to a method for providing such a semiconductor structure.

Abstract: An organic semiconductor device selected from organic diodes, organic field effect transistors, and devices comprising an organic diode and/or organic field effect transistor and a method of producing such a device are provided. The organic semiconductor device comprises at least one semiconducting layer based on a diketopyrrolopyrrole (DPP) polymer. The semiconducting layer may effectively be protected against degradation by radiation and/or oxidation by adding at least one stabilizing agent selected from hydroxybenzophenones, hydroxyphenyl benzotriazoles, oxalic acid anilides, hydroxyphenyl triazines, hindered phenols and/or merocyanines to the DPP polymer layer. The stabilization is effective both during production and during usage of the device, while the device's electronic properties are retained. The stabilizing agent is preferably a UV absorbing agent or an antioxidant or anti-radical agent known from the field of organic polymer technology.
