This invention describes grafted blend compositions, processes for their preparation and fabricated articles, especially foams therefrom. The blends exhibit enhanced melt strength, melt elongation greater than or equal to about 20 mm/s, increased upper service temperature, increased modulus, and increased hardness. The grafted blend compositions have little or no high shear viscosity increase over a corresponding polymer of the same chemical composition absent the coupling agent.

The present invention is at least a two-component thermoplastic elastomeric composition comprising at least one block copolymer wherein the composition has essentially the same comparative elasticity, high temperature serviceability and hardness as the unmodified, undiluted (neat) block copolymer portion of the composition. The composition also shows enhanced thermal stability and processibility and is well suited for fabricating elastic moldings, films and fibers as well as for formulating with asphalts, adhesives and sealants. The novel thermoplastic elastomeric composition comprises (a) from about 50 to about 99 percent by weight of at least one block copolymer and (b) about 1 to about 50 percent by weight of at least one ethylene interpolymer having a density from about 0. 855 g/cc to about 0. 905 g/cc, wherein the ethylene interpolymer in the amount employed is a substantially inert extender of the block copolymer and the composition is further characterized as having: i.

Durable stretch fabrics are made and processed from one or more crosslinked, heat-resistant olefin elastic fibers, e. g. , a substantially linear, homogeneously branched ethylene polymer. The fabrics can be made by any process, e. g. , weaving, knitting, etc. , and from any combination of crosslinked, heat-resistant olefin elastic and inelastic (“hard”) fibers, e. g. , cotton and wool. These fabrics exhibit excellent chemical, e. g. , chlorine, resistance and durability, e. g. , they retain their shape and feel (“hand”) over repeated exposure to processing conditions, e. g. , stone-washing, dye-stripping, PET-dyeing and the like, and service conditions, e. g. , washing, drying, etc.

The invention is related to compositions suitable for the fabrication of pipes, and other articles, with excellent performance properties. The invention provides a composition, comprising a blend, wherein said blend comprises a high molecular weight ethylene-based interpolymer and a low molecular weight ethylene-based interpolymer, and the high molecular weight ethylene-based interpolymer is a heterogeneously branched linear or a homogeneously branched linear ethylene-based interpolymer, and has a density from 0. 922 g/cc to 0. 929 g/cc, and a high load melt index (I21) from 0. 2 g/10 min to 1. 0 g/10 min, and the low molecular weight ethylene-based interpolymer is heterogeneously branched linear or a homogeneously branched linear ethylene-based interpolymer, and has a density from 0. 940 g/cc to 0. 955 g/cc, and a melt index (I2) from 6 g/10 min to 50 g/10 min.

The compositions of the present invention comprise at least one substantially random interpolymer (or blends with other thermoplastics), one or more flame retardant compounds and, optionally one or more flame-retardant synergists. For levels of flame retardants which yield a halogen content of about 0.05 to about 50 parts-per-hundred resin (phr), depending on whether the structure is foamed or not, which in turn result in LOI levels greater than or equal to about 23% oxygen, the compositions of the present invention unexpectedly still retain desirable mechanical properties such as compressive strength, toughness, and elasticity.

Durable stretch fabrics are made and processed from one or more inelastic and one or more elastic fibers, for example, a substantially linear, homogeneously branched ethylene polymer. The fabrics can be made by any process, such as, weaving, knitting, etc., and from any combination of crosslinked, heat-resistant olefin elastic and inelastic (“hard”) fibers, for example, cotton and wool. These fabrics exhibit excellent chemical, resistance (for example chlorine or caustic resistance) and durability, that is they retain their shape and feel (“hand”) over repeated exposure to processing conditions, such as stone-washing, dye-stripping, PET-dyeing and the like, and service conditions, such as washing, drying, etc.
