Title:
改変されたポリプロピレンおよびそのポリマーブレンド
Document Type and Number:
Japanese Patent JP7169142
Kind Code:
B2
Abstract:
A foamable composition includes a semi-crystalline polyolefin having a crystallinity of at least 50% and a poly(sulfonyl azide) of at least 500 ppm based on the total weight of the foamable composition. The foamable composition has a melt strength of at least 20 cN, a melt drawability of at least 100 mm/s, flexural modulus is greater than about 240,000 psi. Such a composition can be used to make a low density foam having a density in the range from 0.005 g/cm3 to 0.6 g/cm3. A resulting foam or a fabricated article, the methods of the composition and the foam are also provided.
