Abstract (en)
[origin: WO2021213771A1] The invention relates to an additive composition with inorganic sulfites, organic derivatives of sulfurous acid and/or thiosulfates, and organic phosphorus compounds, said composition being capable of accelerating the hydrolytic decomposition of a thermoplastic condensation polymer upon working said additive composition into the condensation polymer. The invention additionally relates to a condensation polymer composition which is additivized with an additive composition according to the invention. The invention additionally relates to a method for the hydrolytic decomposition of a thermoplastic condensation polymer and to uses of the additive composition according to the invention and the thermoplastic condensation polymer composition.
