Abstract
The invention relates to the use of amino terminated phosphonamides and their oligomers, as flame retardant additives for a variety of polymers to impart flame retardancy while maintaining or improving processing characteristics and other important properties.
Claims27
A composition comprising amino terminated phosphonamides of general Formula I:
- wherein:
- R is a C1 to C20 alkyl or, optionally substituted, aryl group;
- Z is:
- and each —NH—X—NH— is derived from a polyether amine;
