Amidino thiourea as a secondary accelerator in rubber vulcanization

Abstract

newlineEarlier studies in our laboratory showed that when a nucleophile newlineis used along with disulphide or sulphenamide accelerators the newlinevulcanization is accelerated greatly and the reaction mechanism is generally newlinenucleophilic in nature However it was observed that it also changes with newlinethe systems under review The present study, deals with the use of newlineunsubstituted amidino thiourea aminoimino methyl thiourea AMT V in newlinethe vulcanization studies of different elastorners and their blends One of the newlineaims of this study was to get further proof with regard to the newlinetheory of nucleophilic reaction mechanism in such binary systems Mixes containing thiourea are used as controls newline
