    摘要: The compositions contain, as heat stabilizer, an effective amount of bismuth carboxylate chosen from bismuth succinate, acrylate and terephthalate and their mixtures. In general, this amount is at least 0.05 part and does not exceed 5 parts per 100 parts by weight of vinylidene fluoride polymer. The heat stabilizers according to the invention are suitable both for the thermal stabilization of virgin polymers and for the stabilization/decoloration of thermally degraded waste polymers.
