Abstract: CRYSTAL-CLEAR THERMOPLASTIC MOULDING COMPOSITIONS CONSISTING OF A MIXTURE OF LINEAR SATURATED POLYESTERS, THE DIOL COMPONENT OF WHICH CONSISTS OF ETHYLENE GLYCOL AND A DIOL OF THE FORMULA HO-CH2-CR1R2-CH2-OH, WHEREIN R1 REPRESENTS A HYDROGEN ATOM OR A LINEAR OR BRANCHED ALIPHATIC RADICAL HAVING UP TO 4 CARBON ATOMS, AND R2 REPRESENTS A LINEAR OR BRANCHED ALIPHATIC RADICAL HAVING UP TO 4 CARBON ATOMS, AND OF A STYRENE/ACRYLONITRILE COPOLYMER. FROM THESE CRYSTAL-CLEAR THERMOPLASTIC MOULDING COMPOSITIONS, SHAPED ARTICLES HAVING A HIGH TRANSPARENCY AND A HIGH GLOSS CAN BE MANUFACTURED, IN PARTICULAR ACCORDING TO THE INJECTION-MOULDING PROCESS. OWING TO THEIR GOOD MOULD RELEASE PROPERTIES, THEIR EXCELLENT DIMENSIONAL STABILITY, AS WELL AS THEIR HIGH IMPACT STRENGTH, TOGETHER WITH FAVOURABLE HARDNESS VALUES, THE MOULDING COMPOSITIONS ARE PARTICULARLY SUITABLE FOR THE MANUFACTURE OF HIGH-QUALITY SHAPED ARTICLES.
