IPC: C08J9/10
Filed: 1966-03-25
Abstract: A composition comprising dinitrosopentamethylene tetramine and a stabilizing amount of a hydrated borax, e.g. the decahydrate, is used as a blowing agent in the manufacture of foams.  Example 4 describes the preparation of a foam based on smoked sheet rubber and a styrene-butadiene copolymer.ALSO:Dinitroso-pentamethylene tetramine is stabilized by the addition of hydrated borax, e.g. the decahydrate.  The borax may be used in amounts varying from 5 to 100 parts by weight per 100 part dinitropentamethylenetetramine. The stabilized compound is more resistant to combustion and decomposition by acids. Dinitrosopentamethylene tetramine may be made by nitrosating hexamethylenetetramine with nitrous acid or an alkali metal nitrite in a strong acid.
