Title: Thomas Cuthbert: Innovator in Polypropylene Technology
Introduction
Thomas Cuthbert is a notable inventor based in Houston, TX (US), recognized for his contributions to the field of polypropylene technology. He holds a total of 3 patents, showcasing his innovative approach to polymer compositions and their applications.
Latest Patents
Cuthbert's latest patents include advancements in polypropylene impact copolymers with low haze. This invention provides an in-reactor solution that avoids costly blending and the use of metallocene elastomers. The inventive Ziegler-Natta polypropylene composition includes additional components that may improve properties relative to metallocene-catalyzed elastomers. The invention results in a clear impact polypropylene composition made in-reactor with Ziegler-Natta catalyst, suitable for a wide range of processes. Unlike other clear impact copolymers, it does not rely on high-shear processes or compounding with elastomers. The invention utilizes conventional polypropylene reactor technology to produce these compositions.
Another significant patent involves propylene impact copolymers (ICPs) characterized by a matrix phase comprising from 60 to 95 weight % of a polypropylene polymer. This polymer contains from 0 to 6 mole % of units derived from one or more alpha-olefins other than propylene. The dispersed phase comprises from 5 to 40 weight % of a copolymer derived from a first comonomer, which can be either propylene or ethylene, along with a second alpha-olefin comonomer. The ICPs are particularly well-suited for applications requiring clear, tough polymers, such as thin-walled injection molded articles for frozen food packaging applications.
