Abstract
The title compositions impart fire retardancy to and are not readily leached from various cellulosic substrates. For example, wood treated with a composition comprising a phosphate salt of poly(2-ethyl-2-oxazoline) and a 40:60 mixture of mono- and diammonium phosphate is not only rendered fire retardant but the phosphates exhibit good resistance to leaching.
