Abstract
The characterization study of the molecular structure for some Mannich type condensates, obtained by the replacement of the acid catalysis, is presented. The characterization of the condensation products was conducted by IR and MNR spectroscopy. For the amino-salicylic-formaldehide condensate, the possibility to be used as an activating agent on a standard structure of butadienstyrenic rubber reticulated by a classic vulcanization system based on sulphur and sulphenamide was demonstrated. Keywords: Mannich condensates, structural analysis, vulcanization activating agent
