The invention pertains to heat transfer compositions, particularly to automobile refrigerants comprising a hydrofluoroalkene, an iodocarbon, and at least one lubricant having hydrogen atoms and carbon atoms, wherein no more than 17% of the total number of hydrogen atoms which are attached to a carbon atom are tertiary hydrogen atoms.

[object Object]

A process for the preparation of a fluoroolefin polymer from an azeotropic mixture of monomers having a constant composition, the process including the step of:

Polymer processing simplification

A polyvinylidene difluoride copolymer with a fluoroolefin selected from 2,3,3,3-tetrafluoropropene, 1,1,3,3,3-pentafluoropropene, 2-chloro-pentafluoropropene, hexafluoropropylene, trifluoroethylene, chlorotrifluoroethylene, 3,3,3-trifluoro-2-trifluoromethylpropene and a mixture thereof, wherein the stoichiometry of the co-monomers defines the barrier properties of the copolymer. Such polymers include moisture barrier copolymers and oxygen barrier copolymer. Processes for preparing such moisture barrier copolymers and oxygen barrier copolymers are also provided.

Copolymers for barriers

Provided is a composition comprising (a) at least one halogenated compound selected from the group consisting of C-Chydrofluoroolefin, CFI, and combinations thereof, and (b) an effective stabilizing amount of a sesquiterpene selected from the group consisting of farnesol, farnesene, and mixtures thereof.

Sesquiterpene stabilized compositions

A polymer blend including: (i) a fluoroolefin polymer prepared by a process, including contacting in a first reaction zone an initiator, 2,3,3,3-tetrafluoro-1-propene, and optionally, at least one first ethylenically unsaturated comonomer capable of copolymerizing therewith, wherein contacting is carried out at a first temperature, pressure and length of time sufficient to produce the fluoroolefin polymer; and (ii) an acrylic polymer prepared by a process, including contacting in a second reaction zone an initiator, at least one acrylic monomer selected from the group consisting of: acrylic acid, methacrylic acid, acrylate ester, methacrylate ester, and a mixture thereof, and optionally, at least one second ethylenically unsaturated comonomer capable of copolymerizing therewith, wherein contacting is carried out at a second temperature, pressure and length of time sufficient to produce the acrylic polymer. Processes for preparing the polymer blends are also provided.

Fluorocopolymers blends

A process for the preparation of a fluoroolefin polymer, including the step of:

Fluorocopolymers

A process for the preparation of an allyloxytrifluoropropene derivative of the formula CFCH&#x2550;CR(OCHCR&#x2550;CH) wherein Ris hydrogen, fluoro, or an allyloxy group represented by the formula &#x2014;OCHCR&#x2550;CHwherein R is hydrogen or methyl including contacting (I) a compound represented by the formula CFCH&#x2550;CRRwherein Ris selected from the group consisting of hydrogen, chloro, and fluoro and wherein Ris chloro or fluoro; and (ii) an allyl alcohol derivative of the formula HOCHCR&#x2550;CHwherein R is selected from the group consisting of: hydrogen and methyl; wherein the contacting is carried out in the presence of a base and optionally a solvent at a temperature and length of time sufficient to produce the allyloxytrifluoropropene derivative. A process for the preparation of polymers of the allyloxytrifluoropropene derivatives is also provided.
