ABSTRACT:
Alkali metal polyhydroxy lignin-cellulose polymer is produced by reacting an organic polyhydroxy compound with broken-down alkali metal lignin-cellulose polymer. The alkali metal polyhydroxy lignin-cellulose polymer will react with polyisocyanate to produce foam products which may be used for thermal or sound insulation.
