ABSTRACT:
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.
