Abstract
(EN)
A clear polymer blend comprising: (1) 50-90 wt. % of a glycol copolyester having repeat units from 1,4-cyclohexanedimethanol, terephthalic acid and an alkylene glycol; (2) 45-5 wt. % of a polycarbonate resin; and (3) 5-45 wt. % of an aromatic polyester having repeat units from terephthalic acid, isophthalic acid and Bisphenol A.
(FR)
L'invention concerne un mélange polymère comprenant (1) 50 à 90 % en poids d'un copolyester du glycol comportant des unités de répétition provenant du 1,4-cyclohexanediméthanol, de l'acide téréphtalique et d'un glycol alkylénique; (2) 45 à 5 % en poids d'une résine de polycarbonate; et (3) 5 à 45 % en poids d'un polyester aromatique comportant des unités de répétition provenant de l'acide téréphtalique, de l'acide isophtalique et du Bisphénol A.
