Title: The Innovations of John J Godfrey
Introduction
John J Godfrey is a notable inventor based in Murrysville, PA (US). He has made significant contributions to the field of materials science, particularly in the development of impact-resistant compositions. With a total of 4 patents to his name, Godfrey's work has had a lasting impact on various industries.
Latest Patents
One of his latest patents involves a method of transferring latex particles from an aqueous to an organic medium. This innovative process allows for the preparation of impact-resistant compositions by incorporating acrylic rubber particles or multi-stage emulsion polymer particles containing a rubbery layer in a predominantly methyl methacrylate matrix. The emulsion particles are initially prepared in water as a latex stabilized with anionic groups. The transfer of these particles to a methyl methacrylate medium is achieved by destabilizing the latex with a quaternary ammonium salt and optionally a di- or multivalent inorganic salt. The final step involves separating the water from the methyl methacrylate layer and polymerizing the methyl methacrylate to create the desired impact-resistant compositions.
