Title: Innovations of Pierre Donaldson
Introduction
Pierre Donaldson is an accomplished inventor based in Longview, Texas. He has made significant contributions to the field of thermoplastic polymers, holding two patents that showcase his innovative approach to material science. His work focuses on creating blended compositions that enhance the properties of polymers for various applications.
Latest Patents
Donaldson's latest patents include "Blended compositions, methods for making same, and articles made therefrom." This invention involves blended compositions that can incorporate one or more thermoplastic polymers and organic fillers. The blended composition is designed to achieve a Notched Izod Impact Strength ranging from 20 J/m to about 600 J/m, measured according to ASTM D256-10. Additionally, it features a melt index of approximately 1 g/10 min to about 100 g/10 min, as per ASTM D1238-13, procedure B. The thermoplastic copolymer consists of a blend of polypropylene homopolymer and a copolymer of propylene with a comonomer, which may include ethylene or a Cto Colefin. The copolymer can contain about 0.5 wt % to about 40 wt % of the comonomer, while the blended composition can include about 5 wt % to about 30 wt % of the organic filler based on the combined weight of the thermoplastic copolymer and the organic filler.
Another notable patent is for "High modulus, high ductility polyolefins." This invention provides propylene polymers that can be utilized as thermoplastic polyolefins directly from the reactor system, without the need for further compounding. These polymers exhibit both low-temperature ductility and high flexural modulus, properties that were previously thought to be inversely related in prior art.
