    Abstract: Thermosetting dental materials which contain a peroxycarboxylic acid in addition to other components customarily contained in dental materials and in addition to at least one monomeric ester of methacrylic acid as polymerization catalyst. These dental materials are distinguished from those which contain an organic peroxide as polymerization catalyst by a distinctly better stability during storage.

    Abstract: Heat-hardenable dental mass contains, apart from other usual components, at least one methacrylate ester monomer and a peroxide-type polymerisation catalyst (I) at 0.1-10 wt.% on total polymerisable monomers. (I) is at least one of 8-18C aliphatic peroxymonocarboxylic acids, 6-20C mono- or di-peroxydicarboxylic acids, 7-12C aromatic peroxymonocarboxylic acids, or 8-12C aromatic mono- or di-peroxydicarboxylic acids. More specifically, (I) is present at 1-5 wt.%.
