The invention provides novel latexes of particles of vinylidene fluoride/trifluoroethylene copolymers possessing a more ordered ferroelectric crystalline phase, and hence improved ferro-, pyro-, and piezo-electric properties, and a method for manufacturing the same by emulsion polymerization in the presence of certain cyclic fluorosurfactants.

Vinylidene fluoride and trifluoroethylene containing polymers latexes

The present invention pertains to a process for the manufacture of a crosslinkable fluoropolymer, to said crosslinkable fluoropolymer and the crosslinked fluoropolymer obtainable therefrom, to a film comprising said crosslinkable fluoropolymer or said crosslinked fluoropolymer and to uses of said crosslinked fluoropolymer film in various applications.

Crosslinkable fluoropolymers

The present invention pertains to a process for the manufacture of a multilayer assembly comprising applying at least one patterned substrate onto at least one surface of at least one non-patterned substrate. The present invention also pertains to the multilayer assembly obtainable by said process and to uses of said multilayer assembly in various applications.

Electrically conducting assemblies

The present invention pertains to semi-crystalline fluoropolymer [polymer (F)] comprising: &#x2014;recurring units derived from vinylidene fluoride (VDF); &#x2014;from 10% to 50% by moles [with respect to the total moles of recurring units of polymer (F)] of recurring units derived from trifluoroethylene (TrFE); and &#x2014;from 0.01% to 10% by moles [with respect to the total moles of recurring units of polymer (F)] of recurring units derived from at least one monomer comprising an azide group [monomer (Az)], to a process for its manufacture, to a crosslinkable composition comprising the same, to a process for crosslinking the same and to a method for manufacturing one of electrical and electronic devices using the same.

Crosslinkable vinylidene fluoride and trifluoroethylene polymers

The present invention relates to crosslinkable compositions comprising vinylidene fluoride (VDF)/trifluoroethylene (TrFE) polymers and a fluorine-containing crosslinking agent of formula (A) [agent (Cz)]: {N[S(O)]}&#x2014;(R)&#x2014;R&#x2014;(R')&#x2014;{[S(O)]N}, formula (A) wherein each of g1 and g2, equal to or different from each other, is 1 or 2, each of s1 and s2, equal to or different from each other, is 0 or 1, each of na and na&#x2032; is independently zero or an integer of 1 to 3, provided that the sum na+na&#x2032; is at least 2, each of Rand R&#x2032;, equal to or different from each other, is a C-Chydrocarbon group free of fluorine atoms, nh and nh&#x2032;, equal or different from each other are independently 0 or 1, and Ris selected from the group consisting of i) a C-Cfluorocarbon group, possibly comprising one or more ethereal oxygen atoms, ii) an oligomer comprising copolymerized units of vinylidene fluoride and trifluoroethylene, to a process for the manufacture of said compositions, to a method for curing the same, and to the use of said copolymers in electrical and electronic devices.
