摘要：

Copolymers of tetrafluoroethylene with perfluoroalkenes were prepared by emulsion and y-irradiation techniques. Their compositions were determined by pyrolysis-g.l.c. and their thermal stabilities assessed by thermogravimetric analysis in vacuo. For a particular copolymer the thermal stability decreased with increasing number of side chains. Copolymers containing the same proportion of side chains of different length showed a marked decrease in thermal stability on going from CF3 to C2F5 but further increase in size had relatively little effect. © 1969.
