Abstract (en)
[origin: WO9217519A1] Copolyethylene terephthalate containing from 10 to 25 % by weight of the resin of units deriving from isophthalic acid, having intrinsic viscosity higher than 0.85 dl/g, melting point lower than 220 DEG C and crystallization properties such as to solidify from the melt to the amorphous form also by low cooling rate (1 DEG C/min).
Abstract (fr)
On décrit du copolyéthylène téréphtalate renfermant de 10 % à 25 % en poids de résine d'unités dérivées d'acide isophtalique et présentant une viscosité intrinsèque supérieure à 0,85 dl/g, un point de fusion inférieur à 220 °C et des propriétés de cristallisation permettant une solidification à partir de l'état fondu sous une forme amorphe, même lorsque la vitesse de refroidissement est faible (1 °C/min).
