Abstract
A flame retardant, light stable composition, prepared from a polyolefin, a halogenated hydrocarbyl phosphate or phosphonate ester flame retardant, and an alkoxyamine functional hindered amine light stabilizer. Suitable forms, in which the composition may be provided, include fibers, and fabrics prepared from such fibers.
Claims68
A composition comprising:
- (a) at least one polyolefin;
- (b) at least one flame retardant, comprising a tris(halohydrocarbyl phosphate or phosphonate ester;
- and
- (c) at least one light stabilizer, comprising an alkoxyamine functional hindered amine.
1 more element
A fiber comprising:
- (a) at least one polyolefin;
- (b) at least one flame retardant, comprising a tris(halohydrocarbyl) phosphate or phosphonate ester flame retardant;
- and
- (c) at least one light stabilizer, comprising an alkoxyamine functional hindered amine.
1 more element
A textile structure comprising a plurality of fibers, the fibers comprising:
- (a) at least one polyolefin;
- (b) at least one flame retardant, comprising a tris(halohydrocarbyl)phosphate or phosphonate ester;
- and
- (c) at least one light stabilizer, comprising an alkoxyamine functional hindered amine.
1 more element
A method of preparing a fiber comprising:
- at least one polyolefin;
- at least one flame retardant, comprising a tris(halohydrocarbyl) phosphate or phosphonate ester;
- and
- at least one light stabilizer, comprising an alkoxyamine functional hindered amine;
- the method comprising an extrusion step, of extruding a mixture of the at least one polyolefin, the at least one flame retardant, and the at least one light stabilizer, to obtain a filament.
