Abstract: 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 R1 is C1-C10 alkyl, R2, R3 and R4, which may be the same or different, are, C1-C10 alkyl or C3-C10 cycloalkyl, phenyl, or phenyl-substituted C1-C10 alkyl or C3-C10 cycloalkyl, provided that any two of R1-R4 may optionally be part of a carbocyclic ring, and M+ is a metal ion or a quaternary ammonium ion. When M+ is a quaternary ammonium ion, the initiator may be used in a two-part composition having a (meth)acrylate monomer in both parts and the initiator compound in one part, the two parts being in a weight ratio of about 1:1.
