Title:
PROPYLENE POLYMER AND COMPOSITION CONTAINING THE SAME, MOLDED OBJECT AND LAMINATE COMPRISING THESE, AND PROCESSES FOR PRODUCING PROPYLENE POLYMER AND COMPOSITION CONTAINING THE SAME
Document Type and Number:
WIPO Patent Application WO/1999/067303
Kind Code:
A1
Abstract:
A propylene polymer and a composition thereof which have excellent melt flowability, are reduced in the content of tacky ingredients, have a low modulus, are flexible, give transparent moldings, and are useful as substitutes for soft vinyl chloride resins. The moldings are excellent in low-temperature heat sealability, transparency, and rigidity. The polymer, for example, has a content of stereoregular isotactic pentads (mmmm content) of 30 to 80 %, a molecular weight distribution (Mw/Mn) of 3.5 or lower, and an intrinsic viscosity [$g(h)] of 0.8 to 5 dl/g.
