Abstract
A random copolymer obtained by polymerizing a monomer composition comprising allylamine or a salt thereof and a monomer bearing a phosphorylcholine-like group, comprising 0.01 to 9 mole % of constituent units (A1) derived from allylamine or a salt thereof and 91 to 99.99 mole % of constituent units (A2) derived from a monomer bearing a phosphorylcholine-like group, and having a number-average molecular weight of 50000 to 5000000. This copolymer is excellent in biocompatibility, can be easily fixed on the surfaces of substrates, and exhibit good surface lubricity when formed into films, thus being useful as medical material.
