Abstract
Aminoalkyl piperazine (poly) pyrophosphates as effective flame retardants and thermoplastic polymer resins containing such flame retardants. These flame retarded resins are particularly useful in electrical and electronic components, such as casing or coverings for metal wires or cables.
Claims18
A flame retardant compound having the general formula (I):
- wherein x≥2;
- y is from 2 to 6;
- and z≥1;
- and x≥z, provided that when z is 1, x is ≥2.
A flame retarded thermoplastic resin composition comprising a thermoplastic polymer and a flame retardant compound having the general formula (I):
- wherein x≥2;
- y is from 2 to 6;
- z≥1;
- and x≥z, provided that when z is 1, x is ≥2 and mixtures thereof.
A metal wire or cable covered with a resin, said resin comprising a polyolefin resin and a flame retardant compound having the general formula (I):
- wherein x≥2;
- y is from 2 to 6;
- z≥1;
- and x≥z, provided that when z is 1, x is ≥2, and mixtures thereof.
A plastic molded component adapted for use in electrical or electronic equipment, said component comprising at least one thermoplastic resin and a flame retardant compound having the general formula (I):
- wherein x≥2;
- y is from 2 to 6;
- z≥1;
- and x≥z, provided that when z is 1, x is ≥2, and mixtures thereof.
A method of preparing a flame retardant compound having the general formula (I):
- wherein x≥2;
- y is from 2 to 6;
- z≥1;
- and x≥z, provided that when z is 1, x is ≥2, comprising the step of reacting aminoalkyl piperazine with polyphosphoric acid.
