ABSTRACT:
Disclosed is a novel, flame retarded, non-blooming nylon composition with excellent thermal stability. This composition is comprised of from about 5 to about 35 percent (by weight) of a condensation product derived from brominated phenol by the displacement of bromine from said phenol wherein: (a) said phenol is selected from the group consisting of tribromophenol, tetrabromophenol, pentabromophenol, and mixtures thereof; (b) said condensation product has a repeating structural unit of the formula ##STR1## WHEREIN A IS AN INTEGER OF FROM ABOUT 0 TO ABOUT 4, B IS AN INTEGER OF FROM ABOUT 0 TO ABOUT 2, C IS AN INTEGER OF FROM ABOUT 1 TO ABOUT 5, A PLUS B PLUS C EQUAL 5, Q is a monovalent bond from a carbon atom in the aromatic nucleus of said repeating structural unit to an oxygen atom bonded to an aromatic nucleus, and the polymeric units containing said repeating structural unit comprise at least 80 percent (by weight) of said product; (c) said condensation product contains from about 17 to about 31 percent (by weight) of elemental carbon, from about 0 to about 1.0 percent (by weight) of elemental hydrogen, from about 3 to about 8 percent (by weight) of elemental oxygen, and at least 60 percent (by weight) of elemental bromine; and (d) said condensation product has a molecular weight of at least 750, and one or more polymeric units containing at least four aromatic nuclei per unit comprise at least about 80 percent (by weight) of said product.
