Abstract of the Disclosure BINDER FOR CHEMICAL AGENTS Rubber chemicals, such as accelerators, are often sold in rodform binders. In order for such rods of a rubber chemical to maintain their structural integrity a polymeric binder is utilized. An improved binder for chemical agents is disclosed herein. This binder is a blend of a graft copolymer and a random copolymer; wherein said graft copolymer is comprised of from 55 to 90 weight percent of at least one diolefin monomer and from 10 to 45 weight percent of at least one vinyl aromatic monomer with the backbone of said graft copolymer being derived from at least one diolefin monomer and with the sidechains of said graft copolymer being derived from at least one vinyl aromatic monomer; and wherein said random copolymer is comprised of from 70 to 96 weight percent of at least one vinyl aromatic monomer and from 4 to 30 weight percent of at least one diolefin monomer.
