Fifteen kinds of metal particles were examined to establish whether they could induce the setting of UDMA-based monomer containing BPO without amine under the presence of 4-META at room temperature. FT-IR spectra of the resultant set samples and the monomer were analyzed to see if the setting was caused by the polymerization. The effects of 4-META and BPO concentrations on the setting time were also studied using the metal particles that induced the setting very effectively. As-received Cu, Zn, Mo, Sn, Co, and In particles could initiate the polymerization of the monomer in combination with BPO and 4-META when they were moistened with water. All the three kinds of silver alloy particles examined also could initiate the polymerization, although pure silver metal particles could not. The presence of 4-META drastically shortened the setting time of the mixture of Cu particles and the monomer containing BPO, while higher concentration of BPO in the monomer significantly shortened the setting time.
