Abstract

Through the use of an improved iron-based redox system it is possible to prepare special new, optionally hydrogenated, nitrile rubbers which feature a more uniform monomer distribution and a lower fraction of long-chain branches and hence are distinguished by enhanced flow properties at the same time as very good properties on processing.
