Title: Ann Marie Corey: Innovator in Polymer Technology

Introduction

Ann Marie Corey is a distinguished inventor based in Akron, OH (US). She has made significant contributions to the field of polymer technology, particularly in the development of processes for poly(trimethylene terephthalate) (PTT). With a total of 3 patents to her name, her work has advanced the understanding and application of polymer crystallization and solid-state polymerization.

Latest Patents

Among her latest patents is the invention titled "Apparatus for crystallization of polytrimethylene terephthalate." This innovative apparatus allows for the crystallization of a pelletized product derived from the melt condensation polymerization of 1,3-propanediol and terephthalic acid. The process involves continuous fluidized bed flow of the pellets in water at temperatures ranging from about 65 to about 100°C. This hot-water treatment enhances the crystallinity of the polymer to greater than about 35% and increases pellet density.

Another notable patent is "High temperature solid state polymerization of poly(trimethylene terephthalate)." This process significantly increases the solid-state polymerization rate of PTT. It involves the esterification or transesterification of 1,3-propanediol with an aromatic acid or its dialkyl ester, followed by polycondensation. The resulting product is pelletized and subjected to continuous solid-state polymerization at temperatures between 200 to 225°C, achieving an intrinsic viscosity of 1.3 dl/g or greater.
