    Abstract: 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.

    Abstract: The invention relates to polymer blends, which can be processed like a thermoplastic, whose bulk A) (50 to 90 wt. %) is polymethylmethacrylate or a polymethacrylate resin; and which also contain 5 to 40 wt. % of, as component B), a tough polymer, in particular an ABS polymerizate; and contain 5 to 40 wt. % of, as component C), a polycarbonate or a polyester carbonate. By adding component C), the heat resistance, impact strength and notched impact strength are improved in the known polymethacrylate/ABS blends. With the addition of an impact modifying component D), contained in quantities of 0 to 20 wt. % in the polymer blend, the impact strength and notched impact strength can be further raised. Preferably, recycled polymers can be added as the polymeric mix components.
