Beschreibung
Zusammenfassung:	FIELD: chemistry of polymers. SUBSTANCE: amorphous propylene polymers have the following properties: (a) intrinsic viscosity (η) > Id/Ig; (b) wherein %(gamma) % syndiotactic dyad and (c) less than 2% CH2 groups contained in sequences (CH2)n wherein (d) Bernullianiti index Such propylene polymers having also narrow molecular weight distribution result directly from propylene polymerization reaction as sole product and no special separation is required. Present invention also describes method of preparing said amorphous propylene polymer. EFFECT: improved properties of amorphous propylene polymers. 10 cl, 3 ex, 1 tbl
