Publication number: 20240084051Abstract: Disclosed are support-activators and catalyst compositions comprising the support-activators for polymerizing olefins in which the support-activator includes clay heteroadduct, prepare from a colloidal phyllosilicate such as a colloidal smectite clay, which is chemically-modified with a heterocoagulation agent. By limiting the amount of heterocoagulation reagent relative to the colloidal smectite clay as described herein, the smectite heteroadduct support-activator is a porous and amorphous solid which can be readily isolated from the resulting slurry by a conventional filtration process, and which can activate metallocenes and related catalysts toward olefin polymerization. Related compositions and processes are disclosed.Type: ApplicationFiled: October 11, 2023Publication date: March 14, 2024Applicant: Formosa Plastics Corporation, U.S.A.Inventors: Michael D. Jensen, Kevin Chung, Daoyong Wang, Wei-Chun Shih, Guangxue Xu, Chih-Jian Chen, Charles R. Johnson, II, Mary Lou Cowen
