Stereogradient Polymers Formed by Controlled/Living Radical Polymerization of Bulky Methacrylate Monomers

摘要

The stereochemistry of monomer additions can be recorded on a living polymer chain because the chain continues its growth throughout the polymerization process. If the stereochemistry of the monomer addition can be changed during the living polymerization, it will be reflected accordingly in the changes in the tacticity along the chain. However, unless the chain is living, the products will only be mixtures of the polymer chains with different tacticities and various chain lengths.
