The present disclosure provides a composition comprising or obtained from a reaction mixture comprising a first propylene-based polymer, an olefin block copolymer, and a cure component. The cure component comprises (i) a second propylene/&#x3b1;-olefin copolymer, (ii) a scorch retardant, and (iii) a crosslinking agent.

Thermoplastic vulcanizate with crosslinked olefin block copolymer

A method for processing a thermoplastic material that comprises a microwave-sensitive polymeric region, wherein the method includes exposing the microwave-sensitive polymeric region to microwaves; wherein the exposing results in an increase in the temperature of the polymeric region; and processing the thermoplastic material is disclosed.

Use of microwave energy to selectively heat thermoplastic polymer systems

A composition comprising at least the following:

Interpolymer compositions of ethylene, &#x3b1;-olefin and nonconjugated polyene, methods of making the same, and foam and articles prepared from the same

A microwave-sensitive thermoplastic composition that includes a microwave-receptive additive; and a thermoplastic polymer; wherein the microwave-receptive additive is selected from the group consisting of sepiolite clay, molecular sieves formed from ammonium ion salts or hydrogen ion salts, aluminophosphates, silicoaluminophasphates, silicotitanates, organo-modified clays, molecular sieves or zeolites having a caged organic microwave receptive material, and combinations thereof.

Additives for the use of microwave energy to selectively heat thermoplastic polymer systems

The invention is a device for processing materials comprising a mixing chamber having a valve for removal of the material from the mixing chamber and a piston which fits within the mixing chamber in a manner such that the piston can be moved to remove substantially all material from the mixing chamber via the valve; at least one, preferably at least two, retractable mixing element(s) wherein each of such elements is movable in and out of the mixing chamber through a port wherein the element and port are configured such that during mixing and when the element is withdrawn from the mixing chamber substantially no material is removed from the mixing chamber via the port. The invention is also a method of using such a device and a system comprising use of such devices in an automated or partially automated array.

Retractable pin mixing sample forming device

A fiber is obtainable from or comprises a blend of a propylene based polymer and an ethylene/&#x3b1;-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re&#x3e;1481&#x2212;1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven, knitted or non-woven fabrics can be made from such fibers.

Fibers made from copolymers of ethylene/&#x3b1;-olefins

The present invention relates to crosslinked, olefin elastic fibers where the olefin materials are specifically selected to provide a more robust fiber with higher tenacity and greater temperature stability. Such fibers will be less subject to breakage during fiber spinning and post-spinning (downstream processing) operations including spool formation and unwinding. The specific olefin material used is a blend having an overall melt index (I2) of less than 2.5 g/10 min before crosslinking with a density in the range of 0.865 to 0.885 g/cm. One component of the blend will be characterized as having either a density in the range of from 0.855 to 0.88 g/cmor a residual crystallinity at 80&#xb0; C. of greater than 9 percent but not both. The at least one other component will meet at least whichever characteristic the first component does not meet.

Crosslinked polyethylene elastic fibers

A fiber is obtainable from or comprises an ethylene/&#x3b1;-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re&#x3e;1481&#x2212;1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven or non-woven fabrics can be made from such fibers.

Compositions having good wrinkle resistance and other properties when made into garments an be made from an ethylene multi-block copolymers. The resulting fabrics and garments often have good chemical resistance, heat-resistances, and are dimensionally stable.

Olefin block compositions for stretch fabrics with wrinkle resistance

Knit fabric compositions have now been discovered that often have a balanced combination of desirable properties. Said fibric compositions comprise fibers of olefin block interpolymers or homogeneous branched ethylene polymers or a combination thereof. The fibers are characterized by an amount of crosslinking such that the fabric is capable of being molded.
