COPOLYMER COMPOSITION FOR SEPARATOR AND SECONDARY BATTERY CONTAINING SAME

Abstract: proposed is a copolymer composition including a copolymer and a cross-linking agent, in which the copolymer includes 30% or more to 80% or less by weight of at least one type of monomer units selected from the group consisting of acrylate-based monomer units, acrylonitrile-based monomer units, vinylamide-based monomer units, and acrylamide-based monomer units and 20% or more to 70% or less by weight of vinylpyrrolidone monomer units, based on 100% by weight of the copolymer. in addition, a slurry composition, a separator, and a secondary battery that contains the polymer composition are proposed.
