A pressure-sensitive, flame-retardant adhesive is disclosed comprising a composition fabricated with the polymerization of acrylic esters, dibromostyrene, and vinyl phosphonic acid, with or without acrylic acid, mixed with dispersions of antimony trioxide. The adhesive composition preferably is an emulsion polymer fabricated with dibromostyrene, 2-ethylhexyl acrylate, n-butyl acrylate, and vinyl phosphonic acid, mixed with Sb2O3 in an approximate ratio of 100 parts polymer per about 8-12 parts Sb2O3. Preferred polymers are those containing at least about 11.6% to 15.6% bromine and from 0.25 to 2.5% phosphorous. The adhesive is particularly advantageous in fabricating optical circuit devices.
