The new plastic material which consists of the uneven copolymer of fluoridation vinylidene and kurorotorihuruoroechiren, the applications and manufacturing method

摘要

New plastics made of heterogeneous copolymers of vinylidene fluoride and chlorotrifluoroethylene, consisting of elastomeric nodules of heterogeneous copolymers of vinylidene fluoride and of chlorotrifluoroethylene which are dispersed in a crystalline continuous phase of vinylidene fluoride quasipolymer. …??According to another aspect the plastics are made of heterogeneous copolymers containing overall approximately from 10 to 22 % by weight of CTFE and exhibiting a melting temperature of at least 165 DEG C and a flexural elasticity modulus not exceeding 1000 MPa. The heterogeneous copolymers are obtained by radical copolymerisation in an aqueous medium with introduction of all the comonomers at the beginning of the copolymerisation. …??The plastics can be employed for the manufacture of flexible articles such as flexible tubular articles, cable sheathing, coatings and films. …IMAGE…
