Abstract

Polymer-grease compositions comprising intimate admixtures of thermoplastic polymer and grease. Methods of making and using polymer-grease compositions.

Description

technical field [0001] The present invention relates to polymer-grease compositions comprising an intimate admixture of a thermoplastic polymer and a grease. The invention also relates to methods of making and using the polymer-fat compositions. Background technique [0002] Thermoplastic polymers are used in a variety of applications. However, thermoplastic polymers, such as polypropylene and polyethylene, can present greater formulation challenges when, for example, forming fibers, compared to other polymeric substances. This is because the material and process requirements for fiber preparation are more stringent than those for other forms such as membranes. As far as fiber preparation is concerned, polymer melt flow characteristics are more dependent on the physical and rheological properties of the material than other polymer processing methods. Additionally, the local shear / stretch rates and shear rates in fiber production are greater than in other processes. [00...
