Title: Andrew Keller: Innovator in Oriented Polyolefins
Introduction
Andrew Keller is a notable inventor based in Westbury-on-Trym, GB. He has made significant contributions to the field of materials science, particularly in the development of oriented polyolefins. With a total of 2 patents to his name, Keller's work has implications for various industrial applications.
Latest Patents
Keller's latest patents focus on the composition and extrusion processes of oriented polyolefins. The first patent describes an orientated polyolefin composition that includes an olefin (co)polymer with a weight average molecular weight (Mw) ranging from 30,000 to 1,000,000. This composition features a high molecular weight tail that extends beyond 1,000,000, characterized by a microstructure of parallel chain extended cores and associated lamellar overgrowths. These lamellar overgrowths intermesh with adjacent cores and can sustain a haul-off tension of at least 10 MPa without breaking during extrusion. The process involves extruding the olefin copolymer through a die under a pressure of about 5-10 MPa and at a temperature above the self-blocking temperature, resulting in extrudates with a high modulus.
The second patent also pertains to the extrusion process for preparing oriented polyolefins, emphasizing similar characteristics and processes as the first. This innovation further solidifies Keller's expertise in the field of polymer science.
