CPC classification number: C08F8/00

Abstract: The invention relates to a free-radical initiator composition for polyolefin modification comprising a peroxide-modified inorganic solid particle prepared from: i) a liquid or solution of hydrogen peroxide, and ii) one or more inorganic solid particles, wherein the inorganic solid particles have affinity to the hydrogen peroxide through hydrogen bonding. The invention also relates to a method for preparing a peroxide-modified inorganic composition, comprising mixing a liquid or solution of hydrogen peroxide and one or more inorganic solid particles to form a suspension or gel, and optionally, filtering the suspension or gel and drying the filtered materials to form a solid, peroxide-modified inorganic composition.

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.
