AMORPHOUS PROPYLENE POLYMER AND METHOD OF PREPARATION THEREOF Russian patent published in 1999 - IPC

Abstract RU 2130034 C1

FIELD: chemistry of polymers. SUBSTANCE: amorphous propylene polymers have the following properties: (a) intrinsic viscosity (η) > Id/Ig; (b) %(γ)-%(m) ≥ 0, wherein %(γ) % syndiotactic dyad and (c) less than 2% CH2 groups contained in sequences (CH2)n wherein n ≥ 2; (d) Bernullianiti index (B) = 1±0,2. 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
