ABSTRACT:
Halogenated polyether-polyols lacking terminal primary chlorohydrin and hydroxyl groups are reacted with organic isocyanates to produce semi-rigid or rigid polyurethane foam having excellent physical, mechanical and processing characteristics and good fire-resistance. The polyether-polyols are used individually, as admixtures with each other and/or as admixtures with non-halogenated polyether-polyols.
