Provided is a thermoplastic polyolefin composition that comprises (A) a polypropylene polymer, (B) an elastomer component, (C) an additive component and (D) a scavenger component. Said scavenger component comprises a polyacetoacetate compound that has the Formula (I) defined herein and a metal oxide. Provided also is an article made from said thermoplastic polyolefin composition.

Thermoplastic polyolefin compositions useful for odor reduction

An article comprising a polymeric foam, wherein the polymeric foam contains a continuous polymer matrix defining cells therein, the polymer matrix containing: (a) from 25 to 65 weight percent of one or more olefin block copolymer having a melt index of two grams per ten minutes or more, (b) from 65 to 25 weight percent of one or more chlorinated olefin polymer having a Mooney viscosity less than 60 (ML 1+4, 125&#xb0; C.), and (c) from 5 to 30 weight parts of antimony trioxide relative to 100 weight parts of polymers in the polymeric foam, with weight percent values relative to total polymer weight in the polymeric foam; a process for preparing the article.

Article comprising a flame retardant polymeric foam

A composition comprising (A) from 10 wt % to 90 wt % of a propylene component including at least one propylene based polymer having a propylene content of at least 50.0 wt %, based on the total weight of the propylene based polymer, and a melt flow rate from 0.5 g/10 min to 200.0 g/10 min (ASTM D-1238 at 230&#xb0; C., 2.16 kg); (B) from 1 wt % to 60 wt % of a polyolefin elastomer; (C) from 1 wt % to 20 wt % of a block composite comprising (i) an ethylene-propylene copolymer, (ii) an isotactic polypropylene copolymer, and (iii) a block copolymer including an ethylene-propylene soft block that has a same composition as the ethylene-propylene copolymer of the block composite and an isotactic polypropylene hard block that has a same composition as the isotactic polypropylene copolymer of the block composite; and (D) optionally, from 0.1 wt % to 10 wt % of an antioxidant.

Thermoplastic polyolefin blends including block composites as compatibilizers

The foaming window for making a foam useful in the manufacture of artificial leather is expanded through the use of a foamable composition comprising (A) a propylene-&#x3b1;-olefin copolymer, (B) a molecular melt (MM) comprising 4,4'-oxydibenzenesulfonylazide (DPO-BSA) and an antioxidant, and (C) a blowing agent. The foaming window can be expanded such that foaming can occur at 220&#xb0; C. for 20 to 200 or more seconds.
