Abstract

A polymer is prepared by reaction of ammonia with N,N'-4,4'-diphenylmethanebismaleimide, the polymer obtained is mixed with a blowing agent and with a surface-active agent and the mixture is heated to make it foam. The multicellular materials thus formed are employed for the manufacture of laminated sheets intended for thermal or sound insulation. [FR2279783A1]
