Abstract:
A vinylidene fluoride, hexafluoropropylene copolymer having from about 1 to about 66 weight percent hexafluoropropylene content and having low crystallinity, said copolymer having a DSC melting point defined by the relationship:Melt Temp. (Â° C.)=162.16âˆ’3.192(HFP wt %) when the copolymer has from 1 to 30 weight % hexafluoropropylene, said copolymer having an endotherm on melting defined by the relationship:&Dgr;H=54.81âˆ’1.53(HFP wt %) when the copolymer has from greater than 30 up to less than 36 weight % hexafluoropropylene, and said copolymer having a &Dgr;H of melting of zero when the copolymer has from 36 to 66 weight % hexafluoropropylene.
