Publication number: 20240026066Abstract: The present disclosure relates to the technical field of the epoxy resin, specifically, relates to a preparation method a low-chlorine epoxy resin and use thereof, which can solve the problem of a high total chlorine content in the epoxy resin to a certain extent. The preparation method of a low-chloride epoxy resin comprises: loading a metal oxide as a stationary phase on a grid inside a reaction kettle; the reaction kettle being externally connected to an alternating-current power supply, and under a first pre-set condition, diluted epoxy resin containing a chlorine impurity, as a mobile phase, flowing through the grid loaded with the metal oxide; the epoxy resin containing a chlorine impurity contacting and reacting with the metal oxide to obtain a purified epoxy resin.Type: ApplicationFiled: February 22, 2023Publication date: January 25, 2024Applicant: Zillion Ultrapure Epoxy Resin (Xi'an) Co., Ltd.Inventor: Biao DU

Publication number: 20240026068Abstract: A method of spontaneously patterning a polymer during frontal polymerization includes activating an initiation region of a monomer solution to reaction to initiate a polymerization reaction. A polymerization front is generated and propagates through the monomer solution in a radial or longitudinal direction away from the initiation region. The monomer solution is spontaneously heated downstream of the polymerization front by thermal transport away from the polymerization reaction. Once a localized region of the monomer solution reaches a temperature sufficient for spontaneous initiation of another polymerization reaction, a new polymerization front is generated and propagates through the monomer solution in a circumferential or transverse direction.Type: ApplicationFiled: December 6, 2021Publication date: January 25, 2024Applicant: The Board of Trustees of the University of IllinoisInventors: Jeffrey S.
