ABSTRACT:
A fire retardant additive comprising particles of a polymer of:
1. at least one halogen-containing alpha, betaethylenically unsaturated monomer;
2. at least one bis(hydrocarbyl)vinyl phosphonate having the structure: ##STR1## wherein X is selected from the group consisting of hydrogen, halogen, cyano, aryl, C.sub.1 -C.sub.18 alkyl and ##STR2## wherein R and R' are hydrocarbyl and substituted hydrocarbyl groups which can be the same, different or conjoint; and,
3. at least one third comonomer selected from the group consisting of alpha olefins, vinyl esters of carboxylic acids, C.sub.1 -C.sub.20 alkyl esters of acrylic and methacrylic acid, ethylenically unsaturated dicarboxylic acids, the corresponding anhydrides thereof and the C.sub.1 -C.sub.20 mono and dialkyl esters thereof, amides of ethylenically unsaturated carboxylic acids and the N-methylol and diacetone derivatives thereof, vinyl aryl compounds, C.sub.1 -C.sub.20 alkyl vinyl ethers, aliphatic dienes and glycidyl esters of acrylic and methacrylic acid.
The polymers of the present invention are useful as fire retardant additives for coatings, adhesives, binders, impregnants, laminants, paint bases, other polymers and the like.
