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.
Claims21
A composition comprising amino terminated phosphonamides of general Formula I:
- wherein:
- R is a C1 to C20 alkyl or substituted aryl group;
- Z is:
- and each —NH—X—NH— is derived from an alkanediamine, alkanetriamine, arylamine, or cycloalkylamine having from about 6 to about 20 carbon atoms;
- and
- n is an integer of from 1 to about 20,
- wherein at least one amino terminated phosphonamide Z is
- and the amino-terminated phosphonamide comprises at least about 50% amine end-groups based on the total number of end groups.

A resin composition comprising:
- units derived from amino terminated phosphonamides of general Formula I:
- wherein:
- R is a C1 to C20 alkyl or substituted aryl group;
- Z is:
- and each —NH—X—NH— is derived from an alkanediamine, alkanetriamine, arylamine, or cycloalkylamine having from about 6 to about 20 carbon atoms;
