Title: Gelu Stoeff Stamatoff: Innovator in Polymer Chemistry
Introduction
Gelu Stoeff Stamatoff is a notable inventor based in Newark, DE (US). He has made significant contributions to the field of polymer chemistry, holding 2 patents that showcase his innovative approaches to polymerization processes.
Latest Patents
Stamatoff's latest patents include a process for the polymerization and interpolymerization of propylene, either alone or in combination with ethylene. This process produces polymers and copolymers of propylene using a catalyst that is a coordination complex comprising divalent titanium or other transition metals in a lower valent state. The catalysts are prepared by mixing a higher valent titanium halide or titanate ester with a reducing agent, which can be any organometallic compound. The polymeric products resulting from this process are linear, high molecular weight materials that are useful as plastics, fibers, and elastomers, as well as for producing blends with polyethylene. Another patent involves hydrocarbon interpolymer compositions, which are interpolymers made from ethylene and higher olefinic hydrocarbons containing 5 to 18 carbon atoms per molecule. These interpolymers are valuable for applications in molding, pipes, and wire coatings.
