Abstract

L'invention a pour objet un nouveau type de polypropylène. Il s'agit de polypropylènes élastiques fractionnables ayant une viscosité inhérente de 1,5 à 9 et ne présentant pas de limite d'élasticité, dont la déformation résiduelle (allongement permanent) après traction ne dépasse pas 150 %, contenant 10 % à 80 % en poids d'une fraction soluble dans l'éther diéthylique ayant une viscosité inhérente supérieure à 1,50 et une teneur en polymère isotactique cristallisé d'environ 0,5 % à 5 % en poids, et présentant une biréfringence à l'examen d'une pellicule formée avec cette fraction entre nicols croisés au microscope polarisant, vers 25 degrés C. Ces produits sont utilisables comme matières élastomères, par exemple pour la fabrication de pellicules, filaments et fibres, pneumatiques et tuyaux ou pour le revêtement d'étoffes ou de câbles.
