Title: Graham Lee - Innovator in Polymer Technology

Introduction

Graham Lee is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of polymer technology, particularly in the development of processes that enhance the properties of polyethylene through the incorporation of recycled materials. With a total of 3 patents, his work reflects a commitment to innovation and sustainability.

Latest Patents

One of Graham Lee's latest patents is focused on "Processes for producing polyethylene containing recycled non-polar polymeric material." This patent discloses methods for creating blends of recycled polymeric material and virgin polyethylene. The variability in post-consumer recycled plastic (PCR) composition often leads to inconsistent mixing, resulting in products with subpar mechanical and optical properties. Lee's process allows for better control over the final product's properties, independent of the PCR composition.

Another significant patent is for "Phosphinimine amido-ether complexes." This disclosure presents organometallic complexes that include a metal atom selected from hafnium (Hf) and zirconium (Zr), along with a phosphinimine ligand and an amido-ether ligand. The use of these complexes as olefin polymerization catalysts demonstrates their effectiveness in copolymerizing ethylene with alpha olefins, producing high molecular weight copolymers with excellent comonomer incorporation.
