Title: Innovations of James Carl Williams
Introduction
James Carl Williams is a notable inventor based in Blountville, TN (US). He has made significant contributions to the field of materials science, particularly in the development of advanced polyester compositions. With a total of 8 patents to his name, Williams has demonstrated a commitment to innovation and excellence in his work.
Latest Patents
Among his latest patents, Williams has developed crystallizable shrinkable films and thermoformable sheets made from resin blends. This blend composition includes a first polyester and a second polyester, both containing residues of terephthalic acid, neopentyl glycol (NPG), 1,4-cyclohexanedimethanol (CHDM), ethylene glycol (EG), and/or diethylene glycol (DEG). The first polyester is designed to have a combined amount of NPG, CHDM, and DEG that is less than that of the second polyester. This innovative blend can produce a shrink film that exhibits high ultimate shrinkage, exceeding 65% at 95° C. for 10 seconds, along with a high strain-induced crystalline melting point greater than 190° C.
Another significant patent involves oriented films and shrink films that comprise polyesters containing tetramethylcyclobutanediol and ethylene glycol. This polyester composition includes a dicarboxylic acid component primarily made up of terephthalic acid residues, along with a glycol component that features a specific ratio of tetramethyl-1,3-cyclobutanediol and ethylene glycol residues. The inherent viscosity of the polyester ranges from 0.50 to 0.8 dL/g, showcasing the advanced properties of the materials developed by Williams.
