Title:
BROMINATED P-CUMYLPHENOL AND ITS DERIVATIVE, THEIR PRODUCTION AND FLAME-RETARDANT RESIN COMPOSITION BLENDED WITH THE SAME
Document Type and Number:
Japanese Patent JP3849209
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject compound excellent in light resistance and processability (flowability) when blended in a resin and useful as a flame- retardant for compounding flame-retardant resins frequently used in various electric instruments, etc.
SOLUTION: This brominated p-cumylphenol expressed by formula I [(a) is 1-3 integer; (b) is 1-2 integer] is obtained by brominating p-cumylphenol with a brominating agent (e.g. bromine chloride) in the presence of a catalyst (e.g. aluminum chloride). The compound of formula I preferably has 2.5-4.0 average brominated number, contains 45-62wt.% bromine, is a viscous material at room temperature having pale yellow color, liquid at ≥50°C and contains 0.001-30wt.% of dibromo derivative, 30-95wt.% of tribromo derivative, 1-65wt.% of tetrabromo derivative and 0.01-10wt.% of pentabromo derivative. It is preferable to blend 5-50 pts.wt. of the compound of formula I with 100 pts.wt. of a resin.
