Not all of those with multiple names were of the nobility; landed gentry such as George Henry Lane-Fox Pitt-Rivers consolidated the estates and wealth of several families in their multiple names. These are sometimes created when one spouse has a double-barrelled name and the other has a single surname. Nowadays, such names are almost always abbreviated in everyday use to a single or double-barrelled version. There are even a few ``quadruple-barrelled'' surnames (e.g. Hepburn-Stuart-Forbes-Trefusis, Hovell-Thurlow-Cumming-Bruce, Montagu-Stuart-Wortley-Mackenzie, Plunkett-Ernle-Erle-Drax, Stirling-Home-Drummond-Moray, and the Danish Krag-Juel-Vind-Frijs family). The surname of the extinct family of the Dukes of Buckingham and Chandos was the quintuple-barrelled Temple-Nugent-Brydges-Chandos-Grenville.

In addition, because of various processing factors (principally scorch, this being the premature cross-linking of rubbers due to the influence of heat), the choice of accelerator is governed by different rules to other diene rubbers. Most conventionally used accelerators are problematic when CR rubbers are cured and the most important accelerant has been found to be ethylene thiourea (ETU), which, although being an excellent and proven accelerator for polychloroprene, has been classified as reprotoxic. The European rubber industry has started a research project SafeRubber to develop a safer alternative to the use of ETU.
