摘要：
The invention forms in situ carbon dioxide blown closed cell insulating foams in which blowing is achieved by the evolution of carbon dioxide resulting from partial hydrolysis of polyisocyanate (methyl diphenyl diisocyanate) by water in the resole. The invention uses no additional blowing agent. The reaction is fast and the resulting product has small, closed cells that exhibit long term thermal performance.
