  • Publication number: 20220306783
    Abstract: Disclosed in embodiments herein are ionomers and methods of making the same. The ionomers comprise a neutralized blend of olefin-carboxylic acid copolymers and Group II, Group IIIA, and transition metal salts. The method includes mixing an acid copolymer formed from an ?-olefin monomer and an ?,?-ethylenically unsaturated carboxylic acid having at least one carboxylic acid group with an amine-containing aqueous solution to form an aqueous dispersion containing an amine salt of the acid copolymer. The method further includes mixing a solution of a Group IIA , Group IIIA, or transition metal salt with the aqueous dispersion containing the amine salt of the acid copolymer to exchange at least a portion of the amine salt for the Group IIA , Group IIIA, or transition metal salt, thereby forming the ionic copolymer.

  • Publication number: 20220224749
    Abstract: Examples provide a cloud-based distributed secure shell (SSH) file transfer protocol (SFTP) server system for responding to client requests. A load balancer assigns client requests to available SFTP servers within the cloud based distributed SFTP server cluster. Each SFTP server is hosted on an individual VM associated with a cloud server. An authentication service authenticates the client requests using a single user profile. A registry table on a first cloud storage maintains metadata describing all the data records stored within a second cloud storage. The registry table and the data records are accessible to all the SFTP servers within the server cluster. In this manner, any server within the cluster can authenticate a user and respond to a client request while providing a seamless and uniform user experience while simultaneously reducing resource usage and improving scalability.
