MOISTURE-RESISTANT POLYMER FORMULATIONS WITH PHOSPHORUS-BASED FLAME RETARDANTS

Abstract

A polymer composition comprising: (a) a polymer; and (b) a triazine metal phosphate compound having the formula (I): (AH)a(-)[Mbm+(H2PO4)x1(-)(HPO4)x22(-)](a-)*pH2O; wherein: each (AH)(+) is independently a triazine derivative having the formula (II-1), (II-2) or (II-3); each M is independently Cu, Mg, Ca, Zn, Mn, Fe, Co, Ni, B, Si, Al, Sb, La, Ti, Zr, Ce, V or Sn; a is from 1 to 6; b is from 1 to 14; m is from 1 to 6; x1 is from 1 to 12, x2 is from 0 to 12 and p is from 0 to 5; and a + mb = x1 + 2x2; and wherein:(1) the polymer composition has a water absorption according to ASTM D570 at 90°C and for 14 days in water of less than or equal to 6 wt.-%; or (2) the polymer composition has a ΔDk of less than or equal to 9%, where ΔDk is a percentage change from an initial Dk to a Dk after aging in water at 90°C and for 14 days according to ASTM D150 at 100 MHz; or (3) the polymer composition has a ΔDf of less than or equal to 500%, where ΔDf is a percentage change from an initial Df to a Df after aging in water at 90°C and for 14 days according to ASTM D150 at 100 MHz; or (4) the triazine metal phosphate compound is characterized by a D50 particle size in a range of 0.1 to 45 µm; or (5) any combination thereof.
