  • PROCESS FOR CROSS-LINKING COPOLYMERS USING A SULFUR-CONTAINING CO-AGENT
    Publication number: 20090275703
    Abstract: Process for cross-linking ethylene-?-olefin copolymers comprising the step of combining the copolymer with (a) an initiator capable of generating free radicals and (b) a sulfur-containing co-agent according to formula R—Y—Sx—Y—R. This process results in cross-linked copolymers with improved dynamic properties, tensile strength, delta torque, and/or modulus, without compromising on compression set or aging stability.
