Processing characteristics of alpha‐methylstyrene–methacrylonitrile copolymer

摘要

AbstractProcessing behavior of alpha‐methylstyrene–methacrylonitrile copolymer has been studied in a Brabender Plasticorder and in a capillary rheometer. The copolymer is thermally unstable at a processing temperature of 230°C; however, addition of 2 ethyl acrylate to the copolymer composition enhances processing stability. The terpolymer is processable in the range of 210° to 250°C. However, it is limited by melt fracture at low shear
