Abstract:

A novel nylon‐6/clay/acrylate rubber ternary nanocomposite has been prepared using a process developed by the authors. The process consists of two steps: firstly, an acrylate rubber/clay composite (ARCC) was manufactured by spray‐drying a mixture of clay slurry and irradiated acrylate rubber latex; secondly, the nylon‐6/unmodified clay/acrylate rubber ternary nanocomposite was prepared by blending ARCC and nylon‐6. It has been found that the acrylate rubber particles and clay platelets can help each other to disperse or exfoliate in the nylon‐6 matrix. The silicate layers without organic treatment are exfoliated with the aid of irradiated acrylate rubber particles and the irradiated acrylate rubber particles are uniformly dispersed in the matrix with the aid of clay platelets. The novel nanocomposite prepared using the new process shows simultaneously high impact strength, high flexural modulus and high heat distortion temperature.
