Sulfonyl carbazates containing at least one group of: --SO.sub.2 --NHNH--COO-- wherein the oxygen and the sulfur 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.
含有至少一个--SO.sub.2--NHNH--COO--基团的磺酰基卡巴肼化合物,其中氧和硫原子连接到各种有机基团上,可作为高温气体膨胀聚合物的发泡剂。此外,还发现了新型的多官能团和次烷基取代的磺酰基卡巴肼化合物。
