由于仲胺衍生物促进剂形成的N-亚硝胺具有毒性,所以,推动了寻找替代促进剂的研究工作。伯胺衍生物的次磺酰胺类促进剂,如CBS和了BBS不形成稳定的N-亚硝胺,在许多情况下,可用它们来替换MBS(单独使用或在需要较长焦 Due to the toxicity of N-nitrosamines formed from the secondary amine derivative enhancers, research efforts to find alternative accelerators have been promoted. Sulfonamide accelerators of primary amine derivatives, such as CBS and BBS, do not form stable N-nitrosamines and in many cases can be used to replace MBS (either alone or in the case of longer focal lengths
