Abstract[English]
Thermoplastic compositions include: a. from about 1 wt% to about 70 wt% of a polycarbonate homopolymer component; b. from about 10 wt% to about 40 wt% of a polybutylene terephthalate (PBT) component; c. from about 5 wt% to about 30 wt% of a polycarbonate copolymer component; and d. from about 1 wt% to about 15 wt% of a flame retardant component comprising a cyclic phosphazene compound having an oxaphosphorin ring-containing structure. The compositions have improved heat resistance and flame retardant properties.[French]
L'invention concerne des compositions thermoplastiques comprenant : a. d'environ 1 % en poids à environ 70 % en poids d'un composant homopolymère de polycarbonate ; b. d'environ 10 % en poids à environ 40 % en poids d'un composant polybutylène téréphtalate (PBT) ; c. d'environ 5 % en poids à environ 30 % en poids d'un composant copolymère de polycarbonate ; et d. d'environ 1 % en poids à environ 15 % en poids d'un composant ignifuge comprenant un composé phosphazène cyclique ayant une structure contenant un cycle oxaphosphorine. Les compositions présentent une résistance à la chaleur et des propriétés ignifuges améliorées.
