Publication number: 20240084071Abstract: A method for preparing blends of at least two polymer components is described herein. The disclosed method generally involves controlling relative molecular weights and ratios of the two or more polymer components by selecting a first initiator, a second initiator, and a monomer, and subjecting the reactants to conditions suitable to polymerize the monomer based at least in part on the first and second initiators in connection with obtaining the polymeric blend. The second initiator is advantageously selected based on one or more characteristics associated therewith, based on a characteristic of the first initiator. A polymeric blend produced according to such a method is also provided herein.Type: ApplicationFiled: July 19, 2023Publication date: March 14, 2024Inventors: James M. Lindsey, Bruce L.

Publication number: 20180051156Abstract: A method for enhancing/accelerating the depolymerization of polymers (e.g., those containing hydrolyzable linkages) is described herein. The disclosed method generally involves contacting a polymer comprising hydrolyzable linkages with a solvent and an alcohol to give a polymer mixture in which the polymer is substantially dissolved, wherein the contacting is conducted at a temperature at or below the boiling point of the polymer mixture. A resulting depolymerized polymer can be separated therefrom (including, e.g., monomers and/or oligomers). Such methods can be conducted under relatively mild temperature and pressure conditions.Type: ApplicationFiled: August 16, 2017Publication date: February 22, 2018Inventors: Elizabeth A.

Patent number: 9856588Abstract: An improved process for forming a PTFE mat is described. The process includes providing a dispersion with PTFE, a fiberizing polymer and a solvent wherein said dispersion has a viscosity of at least 50,000 cP. An apparatus is provided which comprises a charge source and a target a distance from the charge source. A voltage source is provided which creates a first charge at the charge source and an opposing charge at the target. The dispersion is electrostatically charged by contact with the charge source. The electrostatically charged dispersion is collected on the target to form a mat precursor which is heated to remove the solvent and the fiberizing polymer thereby forming the PTFE mat.Type: GrantFiled: March 3, 2015Date of Patent: January 2, 2018Assignee: Zeus Industrial Products, Inc.Inventors: Bruce L.
