摘要：
This invention is directed to halodihydrodioxins, their preparation and their polymers, which provide amorphous homopolymers that are resistant to ring opening side reactions. The resulting polymers can be used for films and thermally stable molded objects, coatings for substrates such as wood, glass, paper and metal and for protective packaging. This invention also concerns the preparation of polyhalogenated dioxoles.
