Title: FLUORINATED ACRYLATE BLOCK COPOLYMERS WITH LOW DYNAMIC SURFACE TENSION
Abstract:
The present invention relates to a composition, comprising a binder resin, a block copolymer which comprises at least a block A and a block B, wherein the block A comprises monomer units derived from a compound selected from (meth)acrylic acid, a (meth)acrylic acid ester, a (meth)acrylamide, a vinyl aromatic compound, or any mixture thereof, the block B comprises monomer units derived from a compound selected from a fluorinated (meth)acrylic ester having the following formula (I): H2C=C(R1)(C(0)ORF-1), wherein R1 is H or methyl; and RF-1 is an organic residue containing a perfluorinated C4-6 alkyl group, a fluorinated alpha-olefm having the following formula (II): H2C=CH(RF-2) (II) wherein RF-2 is an organic residue containing a perfluorinated C4-6 alkyl group, i.e. -(CF2)3-5-CF3 or any mixture thereof.
