A method for forming a composition comprising a propylene-based polymer and a co-agent is provided. The method comprises introducing a propylene-based polymer to an extruder and introducing the co-agent to the extruder at a position within the extruder where the temperature is from 23&#xb0; C. to 125&#xb0; C.

Methods of forming compositions and articles

The present invention relates to fibers and nonwovens made from plasticized polyolefin compositions comprising a polyolefin, a non-functionalized hydrocarbon plasticizer and a slip agent.

Polypropylene based fibers and nonwovens

This invention relates to a film or sheet and a process to make a film or sheet having a thickness of 0.5 to 35 mils comprising a blend composition comprising: a) 4 to 50 wt % of one or more polypropylene-based TPO(s); and b) 30 to 80 wt % of one or more ethylene plastomer(s); and c) 0.5 to 35 wt % of one or more non-functionalized plasticizer(s) having a kinematic viscosity at 100&#xb0; C. of 4 to 300 cSt, a pour point of &#x2212;20&#xb0; C. or less, and a flash point of 200&#xb0; C. or more; and d) 0 to 69.5 wt % of one or more filler(s); and wherein the blend composition is calendered into a film or sheet.

Calendered films of plasticized blends of plastomer and impact copolymer

The present invention relates to plasticized polyolefin compositions comprising a polyolefin and a non-functionalized hydrocarbon plasticizer.

Plasticized polyolefin compositions

This invention relates to hetero-phase polyolefin compositions comprising: a) 30 to 99.7 wt % of a polypropylene-based TPO comprising at least 50 wt % propylene and at least 10 wt % ethylene, and b) 0.1 to 20 wt % of one or more non-functionalized plasticizer, and c) 0.2 to 50 wt % of one or more filler; based upon the weight of the composition, and having: i) an MFR of 5 dg/min or more, and ii) a flexural modulus of 500 MPa or more, and iii) a notched Charpy impact strength at &#x2212;30&#xb0; C. of 1 kJ/mor more or a notched Izod impact strength at &#x2212;18&#xb0; C. of 50 J/m or more. These compositions are especially useful in applications such as automotive parts that demand both high stiffness and high impact toughness, as well as good processibility during fabrication.

Plasticized hetero-phase polyolefin blends

The present invention relates to articles made from plasticized polyolefin compositions comprising a polyolefin and a non-functionalized hydrocarbon plasticizer.

Articles from plasticized polyolefin compositions

The present invention relates to a composition comprising more than 25 weight % (based on the weight of the composition) of one or more ethylene polymers having an Mof 20,000 g/mole or more and at least 0.1 weight % of a liquid hydrocarbon modifier where the modifier has:

Modified polyethylene compositions

This invention relates to a method to make an article comprising the steps of combining a semi-amorphous polymer having a heat of fusion of less than 70 J/g with a plasticizer and optionally one or more additives, to produce a polymer concentrate, combining the polymer concentrate with one or more final materials to produce an article precursor; and forming the article at least partially from the article precursor, wherein the polymer concentrate preferably shows no visible phase separation as demonstrated by the polymer concentrate having no visually detectable loss of the plasticizer after a portion of the polymer concentrate is aged on an absorbent surface for 24 hours at 25&#xb0; C. An article produced by the method is also disclosed.

Method to make an article comprising polymer concentrate

The present invention relates to articles made from plasticized thermoplastic polyolefin compositions comprising a thermoplastic polyolefin, a nucleating agent, and a non-functionalized hydrocarbon plasticizer.

Articles from plasticized thermoplastic polyolefin compositions

The present invention relates to radiation resistant plasticized polyolefin compositions comprising a polyolefin and a non-functionalized hydrocarbon plasticizer.
