Abstract

An investigation into the mechanism by which ethylene thiourea (ETU) cross-links polychloroprene (CR) in combination with zinc oxide (ZnO) was undertaken. This was achieved through an examination of the mechanisms of crosslinking CR with ETU and ZnO separately and in unison. Spectroscopic and physical characterization techniques were employed to probe the cross-linking mechanisms of CRusing other standard rubber accelerators and model compounds with analogous structures and functionalities to ETU. These investigations have resulted in the proposal of a new mechanism by which ETU and ZnO can synergistically cross-link CR, in addition to providing new evidence to support concomitant mechanisms already published for cross-linking CR.
