Abstract
Solution halogenation of EPDM (rubbery terpolymer of ethylene, an alpha mono-olefin, and a nonconjugated diene) in the presence of an epoxy compound such as epoxidized soybean oil with or without a poly(alkylene ether) glycol yields a halogenated EPDM of excellent viscosity stability and limited gel content.
