Abstract: A process can be used for manufacturing an acrylic copolymer having increased heat resistance, high transparency, and improved adhesion to metal surfaces. The process involves polymerizing a monomer mixture, optional heating of the copolymer mixture, and removing volatile components from the copolymer mixture by degassing. Moulding compositions containing this copolymer are highly suitable for manufacturing optical elements for optoelectronic devices containing acrylic and metallic or ceramic parts.

Abstract: A fragmentation warhead for a missile includes a warhead casing, an active charge arranged within the warhead casing, and a fragmentation filling arranged within the warhead casing in front of the active charge of the fragmentation warhead in an effective direction of the fragmentation warhead. When the active charge is ignited, fragments are hurled out of the fragmentation filling in the effective direction within a first outlet opening angle. The fragmentation warhead includes a fragmentation damping charge, which is arranged within the warhead casing laterally to the effective direction on the fragmentation filling, to exert a lateral damping pressure on the fragmentation filling upon ignition. The fragmentation warhead includes a fragmentation damping filling, which is arranged within the warhead casing laterally to the effective direction on the fragmentation filling such that the metal powder is released laterally from the fragmentation filling when the active charge is ignited.
