A microcellular rigid vinyl halide foam and a process for producing the foam are provided. The rigid vinyl halide foam exhibits toughness without containing large amounts, if any, impact modifier as part its composition. The microcellular foam can be produced, for example, in a continuous extrusion process. A variety of microcellular rigid vinyl halide foam articles, such as rigid pipe, can be formed. |
