Title: FLUORINATED BLOCK COPOLYMERS
Abstract:
Described herein is a millable fluorinated block copolymer having (a) at least one A block, wherein the A block is a semi-crystalline segment comprising repeating divalent monomeric units derived from at least TFE, HFP and VDF; (b) at least one B block, wherein the B block is a segment comprising repeating dilvalent monomeric units derived from at least HFP and VDF; and (c) a bisolefin monomer, wherein at least (i) the semi-crystalline segment of the A block comprises repeating divalent monomeric units derived from TFE, HFP, VDF, and the bisolefin monomer, (ii) the segment of the B block comprises repeating divalent monomeric units derived from HFP, VDF, and the bisolefin monomer, or (iii) a combination thereof; and wherein the millable fluorinated block copolymer has a modulus of 0.1 to 2.5 MPa at 100°C.
