Abstract

A halogen-free radiation curable flame retardant composition that comprises an end-capped oligomer of a phosphonate polyol and a polyisocyanate and an organic monomer.

Claims

AMENDED CLAIMS [received by the International Bureau on 25 January 1995 (25.01 .95) original claims 1 -17 replaced by new claims 1 -17 (3 pages )]
