1520199 Redox polymerization ESPE FABRIK PHARMAZEUTISCHER PRAPARATE GmbH 20 Dec 1976 [24 Dec 1975] 53153/76 Heading C3P [Also in Division C2] The redox polymerization of unsaturated compounds is effected by contacting the said compounds with a redox polymerization catalyst e.g. a peroxide, and as accelerator, an N,N-bis- (hydroxyalkyl)-3,5-di-t-butyl aniline of the formula wherein R1 and R2 are the same or different and are each H or (C1-4) alkyl. Specified unsaturated compounds are acrylic or methacrylic acid or an ester thereof. The resulting polymers are useful as dental materials.
