A thermoplastic elastomer with increased oil resistance and decreased compression set compared to conventionally cured thermoplastic elastomers may be made from a dynamically vulcanized blend of propylene resin and ethylene/alpha-olefin/non-conjugated diene elastomers via a curing system containing a free radical initiator, a first co-agent including diene-containing polymers with a 1,2-vinyl content greater than 50% by weight, and a second co-agent including multifunctional acrylates containing at least two acrylate groups, multifunctional maleimides containing at least two imide groups, or mixtures of both, where the elastomer gel content in the modified blend is at least 97%.

Polyolefin based sealing element compositions with good oxygen barrier properties particularly suitable for forming sealing elements, for example gaskets and cap liners that are especially useful for sealing containers having products such as liquids or food-stuffs therein. The compositions when formed as sealing elements do not appreciably contribute taste and/or odor to a packaged product including the sealing element. The compositions have desirable rheological properties and are thus readily processable at various temperatures.

The melt strength of an unmodified semi-crystalline polypropylene resin may be increased via thermally reversible ionic bonds and long chain branches formed by the addition of a sufficient amount of at least one peroxygenated polyolefin and a sufficient amount of at least one metallic coupling agent. The peroxide content of the peroxygenated polyolefin ranges from about 1 mmol to 200 mmol total peroxide per kilogram of polymer. The metallic coupling agent is typically at least one metallic salt of alpha, beta-unsaturated carboxylic acids or alpha, beta-unsaturated carboxylic acids where the acid group has been neutralized.

A scratch resistant and mar abrasion resistant thermoplastic polyolefin blend that includes at least one semi-crystalline polypropylene resin component, at least one styrene-based elastomer component, at least one vinyl cyanide component, and at least one processability modifier component. The processability modifier component contains at least one pair of oxygen atoms bonded by a single covalent bond, and is present in an amount sufficient to provide an amount active oxygen of about 4 to 500 parts per million (ppm) of the thermoplastic polyolefin blend.

Thermoplastic vulcanizate blends, or a reaction product thereof, that include at least one propylene resin, at least one ethylene/alpha-olefin/non-conjugated diene elastomer, a curing system, and at least one co-agent may be formed into a foamed blend by the addition of a plurality of expandable polymeric microspheres. Methods of forming such foamed blends and resultant articles are also included. Compared to an equivalent non-foamed blend, such foamed blends are characterized by features that may include low thermal conductivity and decreased density in a closed cell structure with accompanying small cell size, good processability, and colorability.
