MULTILAYER STRUCTURE HAVING A HIGH IMPACT RESISTANCE, HIGH MELT FLOW, LOW

The invention relates to a polymer resin composition, and preferably an acrylic or styrenic polymer composition, which is used in particular as a fabric material for co-extrusion on or lamination onto a structural plastic. The polymeric fabric resin composition comprises a highly efficient minute core-shell impact modifier that can achieve a novel combination of a variety of characteristics: a high impact resistance fabric resin with high melt flow rate and low water mist properties that can achieve better processability and durability suitable for use in high temperature and high humidity environments. Multilayer structures are formed using a polymeric fabric composition on a thermoplastic substrate. 聚合物树脂组合物，并且优选地丙烯酸类或苯乙烯类聚合物组合物，其尤其作为面料材料来使用，所述面料用于在结构塑料上共挤出或层压到结构塑料上。聚合物面料树脂组合物包含一种高效的微小核-壳抗冲改性剂，可实现多种特性的新颖组合：具有高熔体流动速率和低水雾性的高抗冲击性面料树脂，可实现适用于高温和高湿度环境的更好加工性和耐久性。在热塑性基材上使用聚合物面料组合物来形成的多层结构。
