Color-stable rheology controlled polyolefin compositions and methods of making are described. A color-stable rheology controlled polyolefin composition can include a controlled rheology grade thermoplastic polyolefin, and an effective amount of a trisamide-based compound that imparts color-stability to the composition. The color-stable solid-state thermoplastic polyolefin composition can have a Hunter b value color change (&#x394;b) rate of &#x2264;0.03/day when stored at 93&#xb0; C. for 50 days.

Clarified polypropylene for long term color performance

A method of producing a silane cross-linked polyethylene is disclosed which includes maleating a polyethylene polymer to form a maleated polyethylene and reacting the maleated polyethylene with a primary or secondary amino silane to form a silane-grafted polyethylene. The method further includes treating the silane-grafted polyethylene in a moisture curing process to form the silane cross-linked polyethylene.

Process for cross-linked polyethylene production

A thermoplastic polyolefin composition and methods for its use is disclosed. The composition can include a thermoplastic polyolefin and a clarifying agent blend comprising a trisamide clarifier and sorbitol clarifier at a ratio of trisamide clarifier to sorbitol clarifier of 1:2 to 1:40 w/w.

Clarifier blends for optimum performance

A polymeric composition may include a polyolefin or styrenic polymer, a metallic acrylate salt, and an acid neutralizer.

Polymer foams

A method of producing a sliane cross-linked polyethylene is disclosed which includes maleating a polyethylene polymer to form a maleated polyethylene and reacting the maleated polyethylene with a primary or secondary amino silane to form a silane-grafted polyethylene. The method further includes treating the silane-grafted polyethylene in a moisture curing process to form the silane cross-linked polyethylene.

Process for production of cross-linked polyethylene articles

A composite may include polylactic acid, polyethylene, and optionally a compatibilizer. The composite may be formed by combining the polylactic acid with the polyethylene. The composite may be formed into an extruded article.

Composites of polyethylene and polylactic acid

Polymeric compositions and processes of forming the same are discussed herein. The processes generally include contacting a polylactic acid with a reactive modifier selected from epoxy-functionalized polybutadiene, ionic monomer, and combinations thereof.

Modified polylactic acid, polymeric blends and methods of making the same

A high melt strength polypropylene is formed using maleated polypropylene and a combination of coupling agents and acid neutralizers. The maleated polypropylene can be formed using multi-functional monomers. The high melt strength polypropylene can be useful for foaming, sheet extrusion thermoforming, extrusion blow molding, extrusion coating, fiber, film, and the like.

High melt strength polypropylene and methods of making same

A pellet composed of a polymeric blend having a polyolefin and polylactic acid.

Single pellet polymeric compositions

A biaxially oriented film includes a PLA and polyolefin (PLA/PO) blend. The film has a haze of 80% or greater as measured by ASTM-D1003 and a 45&#xb0; gloss of less than 50% as measured by ASTM-D-2457.

Polymeric blends and articles made therefrom

A styrene monomer reclamation process and system is described. The styrene monomer reclamation process includes providing a waste plastic. The waste plastic includes styrenic polymers. The waste plastic is formed into polymer particles. At least a portion of the polymer particles are dissolved in a solvent to form a polymer stream. The dissolved polymer particles are depolymerized to form a styrene monomer stream.

Depolymerization of plastic materials

Fibers and methods of forming the fibers are described herein. The fibers generally include an ethylene based polymer exhibiting a molecular weight distribution of from about 2 to about 8.

Polyethylene fibers and processes of forming the same

A polymer composition may include polyolefin having a molecular weight distribution of greater than or equal to 8 as measured by GPC and a metallic acrylate salt. The polymer composition may be characterized by one or more of: a melt flow rate of from 0.1 g/10 min to 10 g/10 min; a melt flow viscosity between 2,000 Pa&#xb7;s and 6,000 Pa&#xb7;s; a die swell of between 2 and 8; and a die swell characteristic time of between 0.3 seconds and 1.2 seconds. The polymer composition may be in the form of foam. A process of forming foam may include supplying polymer composition including metallic acrylate salt and polyolefin resin, and mixing the polymer composition with foaming agent. A foam may include a polymer composition that includes polyolefin and polar polymer and does not include an ionomer. The foam may have a foam density of less than 0.25 g/cc.
