Publication number: 20230151198Abstract: The present disclosure relates to extruder systems and processes thereof. In at least one embodiment, a method of forming a thermoplastic vulcanizate (TPV) composition includes introducing a thermoplastic polymer to an extruder through a feed throat. The elastomeric polymer is introduced to a melt feeder and an elastomeric polymer melt including the elastomeric polymer is formed. The melt feeder is coupled to the extruder. Elastomeric polymer melt from the melt feeder is introduced to the extruder. The thermoplastic polymer and the elastomeric polymer melt are fed separately to the extruder. The thermoplastic polymer and the elastomeric polymer melt in the extruder are mixed with a plurality of intermeshing screws having a plurality of mixing zones.Type: ApplicationFiled: October 27, 2022Publication date: May 18, 2023Inventors: Mallarie D. McCune, Jianya Cheng, Ronald DeYoung

Patent number: 9994664Abstract: An underwater pelletizing method for pelletizing brittle hydrocarbon resins with low melt viscosity. A feed material comprising the hydrocarbon resin is formed into a melt, extruded through a die into a water bath below the Tg of the hydrocarbon resin to form a plurality of extrudates and cut adjacent the die surface to form a slurry of resin pellets. A graft monomer and/or other reactants, such as a hydrosilylation agent, may be introduced into the resin melt to chemically modify the hydrocarbon resin.Type: GrantFiled: October 3, 2016Date of Patent: June 12, 2018Assignee: ExxonMobil Chemical Patents Inc.Inventors: Eugene R. Uhl, Edward J. Blok, Dennis Kumor, Randal H. Kerstetter, III, Ronald DeYoung

Patent number: 9670348Abstract: A dynamically vulcanized alloy contains at least one isobutylene-containing elastomer, at least one thermoplastic resin, and an anhydride functionalized oligomer grafted to the thermoplastic resin. In the alloy, the elastomer is present as a dispersed phase of small vulcanized or partially vulcanized particles in a continuous phase of the thermoplastic resin and the alloy is substantially absent of any sulfonamides.Type: GrantFiled: October 12, 2015Date of Patent: June 6, 2017Assignee: ExxonMobil Chemical Patents Inc.Inventors: Maria D.

Patent number: 9546251Abstract: This invention relates to the preparation of a dynamically vulcanized alloy comprising at least one elastomer and at least one thermoplastic resin, having a G? at 1% strain and 100° C. as determined according to ASTM D7605 of about 4,500 to about 7,500 kPa. More specifically, the process produces dynamically vulcanized alloys with unique morphological features which have good impermeability and low temperature flexibility. In the process, the thermoplastic resin is added into the extruder in two stages with an intermediate addition of a compatibilizer. Also during the final addition of thermoplastic resin, the elastomeric curatives are added to the extruder.Type: GrantFiled: April 9, 2015Date of Patent: January 17, 2017Assignee: ExxonMobil Chemical Patents Inc.Inventors: Hari P. Nadella, Maria D. Ellul, Ronald DeYoung
