ABSTRACT:
The known compound, 1,2,3,4,9,9-hexachloro-1,4-dihydro-1,4-methanonaphthalene-5,8-diol (I) is an excellent flame retardant for ABS resins and polyurethanes, particularly, polyether-based polyurethanes. Compound (I) also forms novel molecular complexes with weak bases such as pyridine, pyridine HCl, pyridine oxide, dimethylsulfoxide and dimethylformamide, and which are excellent flame retardants for ABS resins. Compound (I) also exhibits unusual synergistic flame retardant effects in ABS resins and other polymers when used together with certain additives that are not themselves flame retardants.
