ABSTRACT OF THE DISCLOSURE Amorphous propylene polymers are disclosed having the following characteristics: (a) intrinsic viscosity [?] > 1 dl/g; (b) %(r) - %(m) > 0, wherein %(r) is the % of syndiotactic diads and %(m) is the % of isotactic diads; (c) less than 2% of the CH2 groups contained in sequences (CH2)n, with n ? 2; (d) Bernoullianity index (B) = 1 ? 0.2. These propylene polymers, which are in addition endowed with a narrow molecular weight distribution, can be obtained directly from the polymerization reaction of propylene as sole product and, therefore, do not require to be separated.
