Investigation of the supermolecular structure parameters of fluorine-containing monofilaments
Tóm tắt
The structure-sensitive coefficient of oriented fluorine-containing monofilaments rises with increase in the melt flow index. A dependence of crystallite defectiveness on the melt flow index has been detected for the tetrafluoroethylene-ethylene copolymer. The strength of monofilaments from a copolymer of tetrafluoroethylene with perfluoroalkyl vinyl ether is less than that of monofilaments from a tetrafluoroethylene-ethylene copolymer; this agrees with the larger values of the structure-sensitive coefficient for the first.
