METHODS FOR MELT-PROCESSING THERMOPLASTIC FLUOROPOLYMERS
摘要
A method comprising melt-processing a first composition. The first composition comprises a first fluoropolymer having a relaxation exponent of from 0.93 to 1.0 and a second fluoropolymer having a relaxation exponent of from 0.30 to 0.92. A method comprising melt-processing a first composition, wherein the first composition comprises a first fluoropolymer having an LCBI of from 0 to 0.1 and a second fluoropolymer having an LCBI of at least 0.2. A method comprising melt-processing a first composition, wherein the first composition comprises a core-shell polymer having a first fluoropolymer portion and a second fluoropolymer portion. The extrusion products have a lower width homogeneity index value than observed in state of the art fluoropolymers.
