Title: Innovations and Contributions of John P. Heller
Introduction
John P. Heller is a notable inventor based in Socorro, NM (US), recognized for his significant contributions to the field of polymer chemistry. With a total of three patents to his name, Heller has made strides in developing innovative methods and apparatuses that enhance the understanding and application of polymers.
Latest Patents
Heller's latest patents include a groundbreaking method for end-quenching the living polymerization of isobutylene with acetyl. This one-pot method allows for the preparation of sulfonic acid-terminated polyisobutylene by sulfonation with acetyl sulfate of living polyisobutylene in a single step. The method facilitates the creation of sulfonated telechelic polyisobutylenes (STPs) through 'inifer' initiated carbocationic polymerization of isobutylene with Lewis acid, followed by the addition of acetyl sulfate at the polymerization temperature or the decomposition temperature of the complex.
Another significant patent is the Miniporopermeameter, which relates to an apparatus and method for determining the permeability and porosity of small sections at and just below the surface of a slabbed sample of porous rock or other materials. This measurement is achieved by forcing air or other gas through a central passageway of a deformable probe tip pressed against the sample's surface. The permeability of the material directly under the probe tip is computed from the flow rate into the sample and the pressure drop between the gas in the probe tip and the ambient atmosphere.
