全卤代-2,2-二低级烷基-1,3-二氧杂环戊烯和全氟-2-亚甲基-4-甲基-1,3-二氧戊环的共聚物

Copolymers of perhalo-2,2-di-loweralkyl-1,3-dioxole, and
perfluoro-2-methylene-4-methyl-1,3-dioxolane
摘要:
The comonomers are perfluorocyclic unsaturated compounds, copolymerized to form amorphous copolymer. Such copolymer forms optically clear tough coating and films.
