摘要：
A resin stabilizer composition which essentially contains: A. AN ORGANOTIN SULFUR-CONTAINING COMPOUND, FOR EXAMPLE, ORGANOTIN MERCAPTIDES, ORGANOTIN MERCAPTO-ACIDS, ORGANOTIN MERCAPTOACID ESTERS, ORGANOTIN SULFIDES, ORGANOTHIOSTANNOIC ACIDS AND THE LIKE, AND B. AN ALKALI METAL BISULFITE ADDITION PRODUCT, INCLUDING ALDEHYDE OR KETONE ALKALI METAL BISULFITES, FOR EXAMPLE, ACETONE SODIUM BISULFITE, CYCLOHEXANONE SODIUM BISULFITE, GLYOXAL SODIUM BISULFITE, FORMALDEHYDE SODIUM BISULFITE, ACETALDEHYDE SODIUM BISULFITE AND CYCLOHEXANONE POTASSIUM BISULFITE. These compositions synergistically contribute to the long term heat stability of vinyl halide resins. Among other advantages, the stabilizing efficiencies of such compositions are excellent and clarity in molded vinyl halide resins can be achieved with these stabilizer compositions.
