COMPOSITION FOR PROCESSING AID

摘要

A composition for processing aids which comprises fluoropolymers. When added in a small amount to a melt-processable resin, the processing-aid composition can sufficiently reduce the extruding pressure necessary for molding the resin. Even when the processing-aid composition further contains an adhesion inhibitor, the fixability of the adhesion inhibitor to the fluoropolymer particle surface is excellent. The processing-aid composition comprises a fluoropolymer (P) and a fluoropolymer (Q) different from the fluoropolymer (P), and is characterized in that the fluoropolymer (P) is a fluoropolymer having (a) a C<SUB>4-21</SUB> linear or branched fluoroalkyl group, (b) a C<SUB>4-21</SUB> linear or branched fluoroalkenyl group, or (c) a fluoroether group having 1-200 repeating units of at least one kind selected from the group consisting of -C<SUB>3</SUB>F<SUB>6</SUB>O-, -C<SUB>2</SUB>F<SUB>4</SUB>O-, and -CF<SUB>2</SUB>O-.
