Title: The Innovations of John P. Thelman
Introduction
John P. Thelman is a notable inventor based in Kenvil, New Jersey. He has made significant contributions to the field of cellulose acetate technology, holding two patents that showcase his innovative approach to material science. His work has implications for various industries, particularly in the production of shaped cellulose acetate articles.
Latest Patents
The first of his latest patents is titled "Process for preparing shaped cellulose acetate article." This invention addresses the evolution of formaldehyde from shaped cellulose acetate articles containing methylolated melamine or guanamine polymers. The process involves adding a cyclic urea compound to the solutions from which the cellulose acetate article is regenerated, reducing the formaldehyde evolution by 1 to 20% by weight based on the weight of the methylolated polymer.
The second patent, "Cellulose acetate solutions containing methylolated polymers," focuses on improving the stability of cellulose acetate solutions. The invention reduces the tendency of these solutions, which contain methylolated polymers of melamine or guanamine, to prepolymerize or gel. This is achieved by adding an amine oxide to the solutions, which also helps to lower the viscosity of the cellulose acetate solutions.
