| Abstract: | Copolymers of acrylonitrile with cinnamonitrile (I), ethyl benzylidenecyanoacetate (II), and benzylidenemalononitrile (III) were prepared in suspension up to high conversions. Films and molded specimens were made from the copolymers and their basic physical and mechanical properties, such as solubility, viscosity, glass transition temperature, and tensile and compressive strength were determined. Further, treatment by heat and ultraviolet light, the permeability of water vapors, and the behavior of films in a weathering tester were studied. |
