Use of high rubber impact modifiers in thermoplastic formulations

A thermoplastic composition comprises a thermoplastic resin (e.g., PVC) and less than 4.0 parts of a core-shell impact modifier per 100 parts by weight of the thermoplastic resin, wherein the core-shell impact modifier has a rubber content of at least 90%. A core-shell impact modifier composition comprises core-shell impact modifier particles having a rubber content that is greater than 92 wt% of the core-shell impact modifier particles. Articles of manufacture made from the thermoplastic compositions are also disclosed. 种热塑性组合物包含热塑性树脂(例如，PVC)以及每100重量份的该热塑性树脂小于4.0份的核-壳抗冲击改性剂，其中该核-壳抗冲击改性剂具有至少90％的橡胶含量。种核-壳抗冲击改性剂组合物包含核-壳抗冲击改性剂颗粒，这些核-壳抗冲击改性剂颗粒具有大于这些核-壳抗冲击改性剂颗粒的92wt％的橡胶含量。还披露了由这些热塑性组合物制成的制品。
