Abstract (en)
[origin: DE19822208A1] A flame retardant, melt stable carbon monoxide copolymer (I) contains a magnesium-calcium carbonate and a basic magnesium carbonate. A flame retardant, melt stable carbon monoxide copolymer (I) comprises: (A) a copolymer of carbon monoxide and alpha -olefinically unsaturated compounds (B) mineral compounds consisting of (B1) a magnesium-calcium carbonate of formula (1) and (B2) a basic magnesium carbonate of formula (2) in a ratio of 10:1-1:10 and optionally (C) an antioxidant (D) an elastomeric polymer or (E) an additive. An Independent claim is also included for a process for the production of (I) by mixing (A) and (B) and optionally (C)-(E) at 180-250 deg C to form a homogeneous molding composition. MgxCay(CO3)x+y.m(H2O) (1) Mgn(CO3)v(OH)2n-2v.w(H2O) (2) x, y = 1 - 5, with x/y \- 1; m = \-0 n = 1 - 6 v = 1 - 5, with nV greater than 1 w = \-0
