A process forming a high MFR polypropylene includes providing a reactor powder polypropylene, the reactor powder polypropylene having a melt flow rate of less than 100 dg/min. The process also includes mixing the reactor powder polypropylene with a free-radical initiator to form a powder/initiator mixture and subjecting the powder/initiator mixture to post-reactor forming. The present disclosure further provides for a vis-broken polypropylene and a polymer article.

Enhanced heat stability polypropylene

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

Polymer foams

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.

An impact copolymer having a flexural modulus (ASTM D-790) of at least about 1,100 MPa; a melt flow rate (ASTM D-1238) of at least about 15 g/10 min; and a maximum load under Dynatup Impact test (ASTM D-3763) of equal to or greater than about 1,700 N at a temperature of less than or equal to about &#x2212;40&#xb0; C. and articles of manufacture from same.
