Document Type and Number:
Japanese Patent JP2013532740
Kind Code:
A
Abstract:
A tetrafluoroethylene copolymer comprising repeating units derived from tetrafluoroethene (TFE) and having a melting point of at least 317°C, a melt flow index (MFI) at 372°C and a 5 kg load (MFI 372/5) of from about 0.60 g/10 min up to about 15 g/10 min, and comprising from 0.12 to 1.40 % by weight based on the weight of the copolymer of units derived from one or more perfluorinated comonomers and wherein the perfluorinated comonomers comprise one or more perfluorinated alkyl vinyl or alkyl allyl ether wherein the alkyl group of vinyl or allyl ether is interrupted by at least one oxygen atom. Also provided are methods of forming a shaped article using the copolymers described above, shaped articles made with those copolymers and compositions containing such copolymers.
