Summary
The phase boundaries as a function of copolymer composition have been established in one polymer/copolymer and two copolymer/copolymer blend systems involving the repeat unit methacrylonitrile. Using the critical conditions for miscibility according to the Flory-Huggins theory, and an overall blend interaction parameter (Bblend) expressed in terms of repeat unit interactions Bi-j, values of BS-MAN and BMMA-MAN have been determined. These are compared with the corresponding acrylonitrile interactions.
