Abstract
Abstract The present invention provides a process for flame-proofing synthetic textiles which comprises passing a textile through an aqueous padding solution containing a polycondensed vinylphosphonate monomer and curing said monomer on said textile, and thereby rendering the textile flame retardant. The present invention also includes the flame retardant textile produced by the process.
