Patent ID: 7052630

Claim:
A process for producing a resin additive composition, said composition comprising: (a) a calix(n+m+λ)arene of formula (2): wherein R 1 , R 2 and R 3 each independently represent a hydrogen atom, a saturated or unsaturated alkyl group which may have one or more substituents, an aryl group which may have one or more substituents, an alkoxyl group which may have one or more substituents, a halogen atom, a nitro group, an acyl group, a carboxyl group, a sulfonic acid group, or an amino group which may have one or more substitaents; R 4 represents a saturated or unsaturated alkyl group which may have one or more substituents, an aryl group which may have one or more substituents, or an anyl group; n represents an integer of 1 to 10; m represents an integer of 0 to 10; l represents an integer of 0 to 10, and n+m+l represents an integer of 4 to 10; R 1 , R 2 and R 3 may be different from each other depending on each unit of n, m and l; M +k represents a metal ion, an NH 4 + ion, or an organic cation; +k represents the valence number of the ion; k represents an integer of 1 to 6; Z −i represents an anion; −i represents the valence number of the anion; i represents an integer of 1 to 6; x represents an integer of 1 to 10; and y represents an integer of 0 to 10, such that the equation: x×k=i×y+n is satisfied; and (b) a functional ingredient which is at least one member selected from the group consisting of a resin flame-retardant, a resin thermal stabilizer, and a resin curing agent, said process comprising precipitating said calix(n+m+l)arene and said functional ingredient together, from a solution of the calix(n+m+l)arene and a solution or suspension of the functional ingredient, such that said functional ingredient is dispersed homogeneously in the solid calix(n+m+l)arene to form a composite composition.
