Abstract:
A VERTICAL, CHLOR-ALKALI ELECTROLYTIC CELL IN WHICH MERCURY CATHODE SURFACES ARE VERTICALLY POSITIONED, EMPLOYING BIPOLAR ROTATABLE ELECTRODES DIVIDING THE CELL INTO A PLURAL NUMBER OF CELL CHAMBERS, WITH EACH CELL CHAMBER SEPA-
RATED FROM ADJACENT CELL CHAMBERS BY CURRENT CUT-OFF MEMBERS LOCATED ON THE CIRCUMFERENCE OF EACH BIPOLAR ELECTRODE.
Abstract:
A flame retardant hardenable composition comprising water glass and a hardener therefor, said composition being incorporated with a resin consisting of a diallyl phthalate polymers of at least 40% by weight of a diallyl phthalate and not more than 60% by weight of comonomers copolymerizable therewith, said resin being incorporated in the composition in an amount of 5-50% based on the total weight of the solids content of said water glass and said resin, and a flame retardant decorative product made essentially of a solid substrate and aforesaid composition.
