Infrared studies of polymer blends containing a copolymer of tetrafluoroethylene and a hexafluoroisopropanol substituted vinyl ether

摘要

An essentially alternating 1:1 copolymer of tetrafluoroethylene and a hexafluoroisopropanol-modified vinyl ether has been recently synthesized. This is an interesting copolymer for both experimental and theoretical studies of the phase behavior of polymer blends because (1) it is amorphous and has a relatively low glass transition temperature (12degreesC); (2) it has a relatively low solubility parameter [approximate to7 (cal cm(-3))(-05)]; (3) it is soluble in moderately polar solvents, and (4) it contains the hexafluoroisopropanol group that is a strong hydrogen bond donor. We report the results of experimental infrared and thermal analysis studies of polymer blends with (co)polymers containing acetoxy, methacrylate, and aliphatic ether groups and compare them to our theoretical predictions of miscibility maps.
