摘要： Polymerization of vinylidene fluoride in an aqueous suspending medium with the involvement of an oil-soluble radical polymerization initiator and in the presence of a suspending agent consisting of a methyl hydroxyethyl cellulose. The use of methyl hydroxyethyl cellulose ensures a substantial reduction in the formation of buildup on the walls of the reactors when compared with other cellulosic suspending agents such as methyl and methyl hydroxypropyl cellulose, which are usually recommended for the polymerization of vinylidene fluoride in an aqueous suspending medium.

摘要： Polymer compositions based on fluoropolymers intended especially for the manufacture of electrical cables and of flexible pipes, comprising, by weight,(A) from 25 to 75% of PVDF homopolymer;(B) from 25 to 75% of a thermoplastic copolymer of VF.sub.2 and of at least one other fluoromonomer, exhibiting a content of 5 to 25% of this other monomer. This other fluorocomonomer may be in particular CTFE (chlorotrifluoroethylene), HFP (hexafluoropropylene) or TrFE (trifluoroethylene). Articles produced from these compositions have good mechanical properties at low temperature.
