HIGH IMPACT BLENDS OF VINYLIDENE FLUORIDE-CONTAINING POLYMERS

Номер: US20180044515A1
Принадлежит:

The invention relates to blends containing polymers of vinylidene fluoride, having low ductile-brittle transition temperatures and having excellent low temperature impact properties while maintaining the positive aspects of unmodified vinylidene fluoride-containing polymers. The blends of this invention are produced by adding a core-shell impact modifier (CSIM) comprised of a polysiloxane core and a shell compatible with vinylidene fluoride-containing polymer. The blends are further characterized by the presence of a heterogeneous copolymer composition comprised of two or more distinct phases and/or at least one flame and smoke suppressant. The preparation of these new blends can be done by conventional thermoplastic compounding techniques such as twin screw compounding; alternatively, the CSIM can be introduced earlier, such as in the latex. The unique properties of the new blends make them useful in end-use applications where those properties provide performance advantages, such as in wires & cables and in oil and gas applications. 1. A resin composition comprised of a vinylidene fluoride-containing polymer and a core-shell impact modifier comprised of a polysiloxane core and a shell of a non-elastomeric polymeric material compatible with the vinylidene fluoride-containing polymer , wherein the resin composition additionally has at least one of characteristics a) , b) , c) or d):a) the resin composition is additionally comprised of at least one flame and smoke suppressant;b) the vinylidene fluoride-containing polymer is a heterogeneous copolymer composition comprised of two or more distinct phases;c) the vinylidene fluoride-containing polymer is in the form of a powder having distinct particles having a weight average particle size on less than 500 nm, or agglomerate particles in the range of 0.5 to 200 microns,d) the resin composition is in the form of an aqueous dispersion.2. The resin composition of claim 1 , wherein the vinylidene fluoride-containing polymer ...
