Title: The Innovative Contributions of Roger Cocco
Introduction
Roger Cocco is a notable inventor based in Saint Symphorien D'Ozon, France. He has made significant contributions to the field of chemistry, particularly in the development of diorganopolysiloxanes. With a total of 4 patents to his name, Cocco's work has had a lasting impact on the formulation of elastomeric materials.
Latest Patents
Cocco's latest patents include innovative methods for preparing end-alkoxylated diorganopolysiloxanes. One of his notable inventions involves the preparation of straight-chain diorganopolysiloxanes with alkoxy endgroups. These materials are designed for use in single-component polysiloxane compositions that remain stable in the absence of moisture but can crosslink into an elastomeric state when moisture is present. This is achieved by reacting a dihydroxydiorganopolysiloxane with a polyalkoxysilane, often in the presence of sodium hydroxide or potassium hydroxide. Another significant patent details the LiOH-catalyzed preparation of functionalized diorganopolysiloxanes, which are also suitable for creating single-component cold-vulcanizable elastomer compositions.
