Abstract
An interpolymer consisting essentially of units derived from vinyl fluoride and at least two highly fluorinated monomers, at least one of the highly fluorinated monomers introducing into the polymer a side chain of at least one carbon atom. Films from these interpolymers have substantially reduced haze, low surface tension, and can be made to form solutions in common polar organic solvents that are stable at room temperature. The extremely low surface tensions obtained with these interpolymer films provide enhanced stain resistance and improved release properties compared to polyvinyl fluoride or known vinyl fluoride interpolymers.

An aqueous dispersion comprising an aqueous medium and particles of an interpolymer dispersed therein, said interpolymer comprising units derived during polymerization from vinyl fluoride and at least two highly fluorinated monomers, at least 30 mol % of said units being derived during polymerization from vinyl fluoride and at least one of said highly fluorinated monomers introducing into the polymer a side chain of at least one carbon atom.
An organic liquid composition comprising a polar organic liquid and an interpolymer, said interpolymer comprising units derived during polymerization from vinyl fluoride and at least two highly fluorinated monomers, at least 30 mol % of said units being derived during polymerization from vinyl fluoride and at least one of said highly fluorinated monomers introducing into the polymer a side chain of at least one carbon atom.
