Low surface tension (meth) acrylate containing block copolymer prepared by controlled radical polymerization
摘要:
A block copolymer including a block of residues of a low surface tension (meth)acrylate monomer; a block of residues of a monomer free of hydroxyl group and amine group residues; and, optionally, a third block of residues of a monomer free of hydroxyl groups and amine groups. The first, second and third blocks are made of different residues from each other and the block copolymer has a polydispersity index of less than 2.5. A controlled radical polymerization method is disclosed to make the low surface tension block copolymers. The method includes the steps of sequentially adding a first monomer composition that is free of hydroxyl groups and amine groups and a second monomer composition that includes the low surface tension monomer to a suitable atom transfer radical polymerization initiator and polymerizing the monomer compositions to form a block copolymer.
