Polymer blends comprises 1) at least one ethylene/&#x3b1;-olefin interpolymer and 2) at least one polyolefin, or at least one styrenic block copolymer, or a combination thereof. Such polyolefins include, but are not limited to, high melt strength high density polyethylene and high melt strength polypropylene. The ethylene/&#x3b1;-olefin interpolymers are random block copolymers comprising at least a hard block and at least a soft block. The polyolefins can be homopolymers or interpolymers. The resulting polymer blends can be used to make flexible molded articles.

A cation exchanging layered material having a cation exchange capacity satisfied by ion-exchangeable organic and inorganic cations, the ion-exchangeable organic cation content of the betastructured cation exchanging layered material being in the range of from ten to ninety-five percent of the cation exchange capacity of the cation exchanging layered material. The structure of the material is unique and is defined as a 'betastructure'. A nanocomposite polymer incorporating such a 'betastructured' cation exchanging layered material with a polymer.

Disclosed are propylene polymer compositions comprising a high crystalline propylene polymer, a substantially linear ethylene polymer, linear ethylene polymer or combinations thereof, an optional filler and an optional additional polymer. Said propylene polymer compositions have improved processability with a good balance of stillness and toughness which demonstrates improved scratch resistance in injection molded articles.
