Abstract: Polymer blends are claimed, contg. (A) 55-99 wt.% of a copolyarylene-ether-sulphone matrix comprising (a1) 91-97 mole% units of formula (I) and (a2) 3-9 mole% units of formula (II); (B) 1-45 wt.% of a disperse phase consisting of copolyarylene-ether-sulphone contg. (b1) 91-97 mole% units (II) and (b2) 3-9 mole% units (I), (C) 0-40 wt.% impact-modifying rubber, (D) 0-60 wt.% fibrous and/or particulate fillers and (E) 0-40 wt.% processing aids and/or additives. Also claimed is (1) a process for the prodn. of these blends by mixing the components in the melt, and (2) fibres, films, coatings and moulded prods. contg. these blends, esp. cooking utensils. Pref. blend contains 60-95 wt.% (A), 5-40 wt.% (B), 0-40 wt.% (C), 0-60 wt.% (D) and 0-40 wt.% (E), or 55-98 wt.% (A), 1-44 wt.% (B), 1-20 wt.% (C) and 0-40 wt.% (E).

Abstract: In a process for renewal of plate-shaped food trays of amorphous or partially crystalline thermoplastics, having a flat central portion and a raised edge, the used trays, in the cleaned and dried state, are subjected to (a) heating to 1-200 deg.C above the glass transition temp. of amorphous thermoplastics or the melting point of partially crystalline thermoplastics; and (b) surface stamping in a press at a pressure of 1-2000 bars.
