Blended compositions that can include one or more thermoplastic polymers and one or more organic fillers and methods for making and using same. The blended composition can have a Notched Izod Impact Strength of at least 20 J/m to about 600 J/m, measured according to ASTM D256-10, and a melt index of about 1 g/10 min to about 100 g/10 min, measured according to ASTM D1238-13, procedure B. The thermoplastic copolymer can include a blend of a polypropylene homopolymer and a copolymer of propylene and a comonomer. The comonomer can include ethylene, a Cto Colefin, or any mixture thereof. The copolymer of propylene and the comonomer can include about 0.5 wt % to about 40 wt % of the comonomer. The blended composition can include about 5 wt % to about 30 wt % of the organic filler based on the combined weight of the thermoplastic copolymer and the organic filler.

The blend has a single peak in an ATREF profile eluting above 30&#xb0; C., and has a coefficient of viscosity average molecular weight (CMv) less than &#x2212;0.0032 in the log(calculated Mv) versus elution temperature, said CMv calculated in the range of elution temperatures from 70&#xb0; C. to 90&#xb0; C. The Mv is the viscosity average molecular weight.

Polyethylene compositions, methods of making the same, and articles prepared therefrom

The invention relates to functionalized interpolymers derived from base olefin interpolymers, which are prepared by polymerizing one or more monomers or mixtures of monomers, such as ethylene and one or more comonomers, to form an interpolymer products having unique physical properties. The functionalized olefin interpolymers contain two or more differing regions or segments (blocks), resulting in unique processing and physical properties.

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.
