Abstract
The present invention relates to a stabilizer system for halogenated polymers comprising, as component (A), calcium monocarbonatohydroxodialuminate of the formula (A) CamAl2(OH)6+2(m-1)CO3*nH2O (A), where m=from 3.8 to 4.2, and n=from 0 to 3, and, as component (B), a catena-2,2′,2″-nitrilotrisethanolperchloratolithium or -sodium coordination polymer (B1) with a monomer unit of the formula where Mt=Li or Na, An=OClO3 and q=1, and/or a quaternary or ternary ammonium or phosphonium perchlorate (B2). The present invention further relates to compositions and articles comprising these stabilizer systems, and to the use of the systems and compositions.
