    摘要： Highly transparent, impact-resistant molding compositions based on polymethyl methacrylate (PMMA), having excellent color stability both during processing at high temperatures, as well as when under thermal stress, as a result of multiple processing with simultaneously high weathering stability and stability of the optical characteristics with the effect of water. Preparation is carried out according to a multi-step extruder process, wherein an extruder for the melt coagulation and one for the compounding are connected in series. Addition of small quantities of reducing inorganic phosphorous compounds at a later stage provides prolonged effectiveness.

    摘要： The present invention relates to a concentrator for concentrating solar radiation and to the production thereof from polymeric materials. The concentrator according to the invention can be used in photovoltaically or in particular in solar thermally usable systems. The concentrator according to the invention allows for the efficient concentration of solar radiation onto objects such as solar cells, independent of the geometry thereof. This relates, for example, to the surface of a solar cell as it is used in concentrating photovoltaics, and also an absorber tube as it is used in concentrating solar heating, for example in the scope of the parabolic trough technology.
