摘要: Disclosed are chlorine containing polymer compositions containing stabilizers which impart good thermal stability. PVC compositions and, in particular, flexible PVC compositions containing stabilizers which are oligomeric and/or polymeric aminouracyls exhibit high thermal stability as evidenced by improved resistance to yellowing and blistering upon extended exposure to high temperatures.
