Abstract: The invention relates to copolymers and molding compounds having reactively bonded sulfur and an overall low sulfur content. The copolymers and molding compounds of the invention are substantially colorless and odorless while sufficiently flame-retardant and can be used in the building industry and electrical industry.

Abstract: A coating for a carrier material made of a steel material for joining to an aluminum material includes a first sublayer on the core part side and a second sublayer on the outside. On average, the coating includes approximately 1 to 10 wt. % silicon and iron, the remainder being aluminum. The first sublayer at least approximately includes 42 wt. % iron, 11 wt. % silicon, and no more than approximately 45 wt. % aluminum, which constitutes the remainder, and has a thickness of no more than approximately 3.5 ?m. The second sublayer includes approximately 1 to 10 wt. % silicon, the remainder being aluminum, and has a thickness of approximately 5 to approximately 95 ?m.
