    摘要： This invention relates to polyamides which have been modified with special silicone graft rubbers to render them impact resistant and are tough at low temperatures and have high processing stability even at high temperatures and good surface properties.The moulding compounds, which are distinguished by excellent mechanical properties even at low temperatures, consist of at least 40% by weight of polyamide and special graft rubbers with a multishell core/sheath structure having a silicone-based core.
