LAKTAMBLANDNING INNEHALLANDE TETRAKLORETEN FOR FRAMSTELLNING AV POLYAMIDSKUM GENOM ANJONISK POLYMERISATION

摘要

A process for the manufacture of polyamide foams by anionic polymerization of lactams, in which from 0.1 to 15% w/w tetrachloroethylene is added to the reaction mixture to be foamed. The resulting foams are very tough, even at low temperatures.
