Specifically, a flashline heater configured according to present embodiments may provide more time than is required for complete vaporization of liquid hydrocarbons that are not entrained within a polymer fluff produced within a polymerization reactor. Such extra time may allow for liquid hydrocarbons that are entrained within the polymer fluff to be vaporized.Type: GrantFiled: March 1, 2018Date of Patent: May 28, 2019Assignee: Chevron Philips Chemical Company LPInventors: John D. Hottovy, Scott E. Kufeld

Patent number: 10301406Abstract: A flame-retardant aconitic acid-derived monomer, a process for forming a flame-retardant polymer, and an article of manufacture comprising a material that contains a flame-retardant aconitic acid-derived monomer are disclosed. The flame-retardant aconitic acid-derived monomer can have at least one phosphoryl or phosphonyl moiety with functional groups that can participate in a polymerization reaction, such as allyl, epoxy, or propylene carbonate functional groups. The process for forming the flame-retardant polymer can include forming an aconitic acid derivative, forming a phosphorus-based flame-retardant molecule, and reacting the aconitic acid derivative with the phosphorus-based flame-retardant molecule to form a flame-retardant aconitic acid-derived monomer, which is then polymerized. The aconitic acid derivative can be synthesized from aconitic acid obtained from a bio-based source.Type: GrantFiled: June 1, 2017Date of Patent: May 28, 2019Assignee: International Business Machines CorporationInventors: Sarah K. Czaplewski, Brandon M. Kobilka, Joseph Kuczynski, Jason T. Wertz, Jing Zhang

Patent number: 10301407Abstract: The present invention relates to a vinyl chloride-based polymer which has improved thermal stability and a method for preparing the same. The vinyl chloride-based polymer includes silicate compound derived units, and a dehydrochloric acid (dehydrochlorination) reaction due to heat or ultraviolet rays may be suppressed, and thus, thermal stability may be improved, and discoloration and deformation of physical properties may be prevented. Accordingly, the vinyl chloride-based polymer and the method for preparing the same may be readily applied to industries requiring a vinyl chloride-based polymer, for example, industries related to a vinyl chloride-based resin and molded articles thereof.Type: GrantFiled: October 7, 2016Date of Patent: May 28, 2019Assignee: LG Chem, Ltd.Inventors: Jung Rae Lee, Kyung Seog Youk, Heung Kwon Bae, Hyun Min Lee

Patent number: 10301408Abstract: An oxo-nitrogenated vanadium complex having the general formula (I): in which: —R1, R2, R3, R4, R5, R6 and R7, mutually identical or different, represent a hydrogen atom; or are selected from optionally halogenated, linear or branched C1-C20, preferably C1-C15, alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups; —X1 and X2, mutually identical or different, represent a halogen atom such as, for example, chlorine, bromine, iodine, preferably chlorine; or are selected from linear or branched C1-C20, preferably C1-C15, alkyl groups, —OCOR8 groups or —OR8 groups in which R8 is selected from linear or branched C1-C20, preferably C1-C15, alkyl groups; —Y is selected from ethers such as, for example, diethyl ether, tetrahydrofuran (THF), dimethoxyethane, preferably is tetrahydrofuran (THF); —n is 0 or 1. Said oxo-nitrogenated vanadium complex having the general formula (I) may advantageously be used in a catalytic system for (co)polymerizing conjugated dienes.Type: GrantFiled: December 23, 2015Date of Patent: May 28, 2019Assignee: Versalis S.p.A.Inventors: Guido Pampaloni, Giovanni Ricci, Anna Sommazzi, Francesco Masi, Giuseppe Leone
