在熔融态下具有较高流动性水平的新型抗冲改性热塑性组合物
Abstract:
本发明涉及组合物，所述组合物包括如下：45‑94.95重量％的由至少一种聚酰胺组成的基体；0.05‑20重量％的至少一种预聚物，聚酰胺基体的重量比例和预聚物的重量比例分别为60‑99.9重量％和40‑0.1重量％，相对于聚酰胺预聚物的总量；5‑45重量％的至少一种抗冲改性剂；和0‑20重量％的添加剂，所述组合物在熔融态下具有比没有预聚物的相同组合物更高的流动性水平。
Abstract(English):

The invention relates to a composition comprising: between 45 and 94.95 wt.% of a matriXconsisting of at least one polyamide; between 0.05 and 20 wt.% of at least one prepolymer, the proportion by weight of the polyamide matriXand that of the prepolymer being respectively between 60 and 99.9 wt.% and between 40 and 0.1 wt.% in relation to the total amount of polyamide-prepolymer; between 5 and 45 wt.% of at least one impact modifier; and between 0 and 20% of an additive, said composition having a higher level of fluidity in the melted state than the same composition without prepolymer.
