Abstract
Flameproofed polymeric organic materials, e.g. regenerated cellulose, which include bis-(2-oxo-1,3, 2-dioxaphosphorinanyl) oxides, bis-(2-thiono-1,3,2 -dioxaphosphorinanyl) oxides and 2-oxo-1,3,2-dioxaphosphorinanyl-2'-thiono-1',3',2'-dioxaphosphorinanyl oxides, having at least one substituent on the dioxaphosphorinane rings, as flameproofing agents, and their production. Some of the flameproofing agents are new compounds and are included in the invention.
