Gradient copolymers – Preparation, properties and practice

Abstract Gradient copolymers are members of a unique class of copolymer in which the monomer composition changes gradually from one end of the polymer chain to the other. In general, the properties of copolymers are strongly dependent on composition and sequence distribution, and hence gradient copolymers can exhibit unique properties compared to those of block and statistical copolymers. This review presents an overview of the methods of synthesis of gradient copolymers using the range of available polymerization techniques, and compares and contrasts the properties of gradient copolymers with properties of the analogous block and statistical copolymers.
