Sulfonyl carbazates containing at least one group of: --SO.sub.2 --NHNH--COO-- wherein the oxygen and the sulphur atoms attach to various organic groups are useful as high temperature blowing agents for gas-expandable polymers. Additionally, novel polyfunctional and secondary-alkyl substituted sulfonyl carbazates have been discovered.
