Abstract
The present invention relates to a process comprises mixing, at temperatures between about about 90.degree. C. to 300.degree. C., a first reactant solution comprising less than about 5.times.10.sup.-3 moles/l of at least one antimony compound and at least one first diol having having 2 to about 16 carbon atoms with a second reactant solution comprising less than about 30.times.10.sup.-3 moles/l of at least one phosphorus stabilizer compound and at least one second diol to form sub-visual molecular aggregates comprising antimony phosphate derivatives. Sub-visual molecular aggregates comprising antimony phosphate derivatives which are stable in suspension are also disclosed.

A process comprises mixing, at temperatures between about 90.degree. C. to 300.degree. C., a first reactant solution comprising less than about 5.times.10.sup.-3 moles/l of at least one antimony compound and at least one first diol having 2 to about 16 carbon atoms with a second reactant solution comprising less than about 30.times.10.sup.-3 moles/l of at least one phosphorus stabilizer compound and at least one second diol to form sub-visual molecular aggregates comprising antimony phosphate derivatives.
A process comprises mixing a first reactant solution comprising less than about 5.times.10.sup.-3 moles/l of at least one antimony compound and at least one first diol having 2 to about 16 carbon atoms with a second reactant solution comprising less than about 30.times.10.sup.-3 moles/l of at least one phosphate ester and at least one second diol to form a mixture;
- and heating said mixture to temperatures between about 25 to about 300.degree. C. for time periods between about 5 minutes to about 1 week, to form sub-visual molecular aggregates comprising antimony phosphate derivatives.
A composition comprising at least one glycol and sub-visual antimony phosphate derivative particles which are suspended in said glycol.
