Abstract
Abstract Finely divided particulate inorganic antimony compounds which are surface modified with an organic titanium compound having the formula Ti(OR).sub.4 wherein each R is independently an alkyl, aryl, cycloalkyl, or vinyl group containing from one to about 18 carbon atoms, or Ti(OR').sub.2 (OYX).sub.2 wherein X is oxygen or nitrogen, Y is a two- or three-carbon atom chain, and R' is equal to R, H or the ligand represented by XYOH are described. These surface modified antimony compounds may be incorporated into various organic resin and elastomer systems to improve the flame-retardant properties of these materials.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
72 words
A finely divided particulate inorganic antimony compound surface modified with an organic titanate having the general formula Ti(OR).sub.4 (FORMULA I) wherein each R is independently an alkyl, aryl, cycloalkyl, or vinyl group containing from one to about 18 carbon atoms, or Ti(OR').sub.2 (OYX).sub.2 (FORMULA II) wherein X is oxygen or nitrogen, Y is a two- or three-carbon atom chain, and R' is equal to R, H, or the ligand represented by XYOH.
Claim 2
Dependent Claim
72 words
A finely divided particulate inorganic antimony compound surface modified with an organic titanate having the general formula Ti(OR).sub.4 (FORMULA I) wherein each R is independently an alkyl, aryl, cycloalkyl, or vinyl group containing from one to about 18 carbon atoms, or Ti(OR').sub.2 (OYX).sub.2 (FORMULA II) wherein X is oxygen or nitrogen, Y is a two- or three-carbon atom chain, and R' is equal to R, H, or the ligand represented by XYOH.
Claim 3
Dependent Claim
22 words
The compound of claim 1 wherein the antimony compound is surface modified with up to about 10% by weight of the titanate.
Claim 4
Dependent Claim
19 words
The compound of claim 1 wherein the antimony compound is an antimony oxide, antimony oxychloride, or a metal antimonate.
Claim 5
Dependent Claim
16 words
The compound of claim 1 wherein Y contains from about two to about ten carbon atoms.
Claim 6
Dependent Claim
31 words
The compound of claim 1 wherein the titanate has a general formula Ti(OR).sub.4 (FORMULA I) wherein each R is independently an alkyl group containing from one to about 18 carbon atoms.
Claim 7
Dependent Claim
13 words

Claim 9
Dependent Claim
37 words
A method of improving the flame-retardant properties of organic resins and elastomers comprising incorporating into said resin or elastomer, an amount of the surface-modified antimony compound of claim 1 which is effective to improve the flame-retardant properties.
