POLYPROPYLENE HAVING LOW ISOTACTICITY AND RELATIVELY HIGH MELTING POINT |
| 摘要 |
A propylene polymer having the following characteristics: (E) 50 </= mmmm </= 85 %; (F) <i>Tm</i> >/= 50. epsilon <0.0124(mmmm)>; (G) Esol </= 5 wt %; and (H) 2,1-regioerrors </= 0.05 %; wherein mmmm represents the isotacity ba the pentad indication, Tm represents the melting point of the polymer, Esol represents the posrtion of the polymer soluble in boiling diethyl ether and 2,1 regioerrors represents the head-to-head insertions on the polymer chain. |
