A two-component initiator system having accelerators for curing polymerizable materials comprising the following components: (a) a hydroperoxide compound containing one or more hydroperoxide groups that are bound to a tertiary carbon; (b) a thiourea derivative; and (c) as accelerator, a copper compound which is soluble in the preparation is preferably free of amine and is particularly suited for polymerizable dental compositions.

of 2-mercaptoethylguanidine (MEG) have been synthesized as potential radioprotective agents with the assumption that increase in liposolubility of MEG will improve its radioprotective ability. The compounds were obtained by reaction of bromoethylamine with the appropriate alkylated thiourea to give the corresponding aminoethylisothiouronium bromide hydrobromide, which was rearranged to the desired MEG
