Furans, compositions containing them, polyurethane or isocyanurate foam compositions derived therefrom, process for fireproofing them and process for trimerisation of these furans.

摘要

Especially furans and compositions containing them. These new furans have hydroxyl end groups and are capable of forming active components of rigid urethane and isocyanurate compositions exhibiting potential hazards in relation to fire which are reduced when compared with the known compositions, while being compatible with the other known constituents of materials forming urethane and isocyanurate. Application to the manufacture of rigid polyurethane and polyisocyanurate foams.
