Abstract
A method of making block copolymers utilizing free-radical polymerization and subsequent polymer conjugation is described. A disulphide functional radical initiator was used to polymerize methacrylic acid and 3-acrylamidophenylboronic acid. After purification, the disulphide bond of the end group was cleaved, revealing a thiol group which was used for subsequent conjugation to a polylactide containing the complementary maleimide functional group. The method is versatile and can be applied to the synthesis of various block copolymers without requiring the use of controlled/living radical polymerization methods.
A versatile method of making block copolymers using conventional radical polymerization of acrylic monomers from a functional radical initiator followed by ‘click’ ligation is described.![]()
