Title:
PROPYLENE POLYMER
Document Type and Number:
Japanese Patent JP2006124452
Kind Code:
A
Abstract:
To provide a polypropylene polymer containing little ethylene chain component to cause the deterioration of physical properties.
The propylene copolymer is composed of a part (Dsol) soluble in n-decane at room temperature and a part (Dinsol) insoluble in n-decane at normal temperature. The GPC molecular weight distributions (Mw/Mn) of both Dsol and Dinsol are ≤4.0, the P(E3)/P(E5) ratio of the 720 cm-1 peak height P(E5) and the 730 cm-1 peak height P(E3) in the IR measurement of the polymer is ≥0.9, Dsol/(Dsol+Dinsol)×100 is ≥5%, and the intrinsic viscosity ([η](dl/g)) of Dsol is ≥1.5.
