Title:
NON-FLUORINATED BLOCK COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2020/067448
Kind Code:
A1
Abstract:
Provided is a non-fluorinated block copolymer comprising at least one block segment (A), wherein the block segment (A) comprises a repeating unit formed from one or more types of acrylic monomer having a long-chain hydrocarbon group containing 7–40 carbon atoms, and the block copolymer imparts superior liquid repellency to a base material such as fibers. The non-fluorinated block copolymer preferably contains a segment (B) constituted by at least one of: (B1) a block segment comprising a repeating unit, different from that of segment (A), that is formed from an acrylic monomer having a long-chain hydrocarbon group comprising 7–40 carbon atoms; (B2) a block segment comprising a repeating unit formed from an acrylic monomer not having a long-chain hydrocarbon group; and (B3) a random segment formed from at least two types of acrylic monomers.
