Zusammenfassung:1 110 Quaternary boron salts are used as initiators of polymerisation in adhesive compositions for bonding low surface energy substrates such as polyolefins. The quaternary boron salts are of the formula I wherein Ris C-Calkyl, Particular examples of initiator compounds include sodium tetraethyl borate and lithium tetraethyl borate, lithium phenyl triethyl borate and tetramethylammonium phenyl triethyl borate.
