Processing characteristics of alpha-methylstyrene-methacrylonitrile copolymer
Processing 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 pro...

| Zusammenfassung: | Processing 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 rates. |
