ABSTRACT:
Copolymers of perfluoro(1,3-dimethyl-2,2-dioxole) with perfluoro(butenyl vinyl ether) and, optionally, with a third comonmer are amorphous in all monomer proportions, and soluble in perfluoro(2-butyl tetrahydrofuran). These copolymers are suitable in many high technology applications, especially where solubility is important, e.g., in applying coatings to substrates or articles for protection against mechanical, chemical, or environmental hazards. Dipolymers of the present invention have lower glass transition temperatures than dipolymers of perfluoro(1,3-dimethyl-2,2-dioxole) with tetrafluoroethylene having the same monomer proportions.
