Abstract
The present invention relates to the thermal stabilization of halogen containing polymer compositions. More particularly the invention relates to a tin stabilizer composition for chlorine containing polymers, and more specifically a composition comprising a mono alkyltin compound as major compound of the tin stabilizer composition and a co-stabilizer.The present invention relates as well to the use of a mono alkyl tin compound as major compound of the tin stabilizer and a co-stabilizer as heat stabilizers for processing chlorine containing polymer composition.
