Highly functionalized polymers represent a broad family of polymers with multiple functionalities attached to each repeat unit in the backbone. These can be small molecule functional groups or polymer sidechains grown or grafted from these functional groups. The latter leads to a class of polymers defined as comb polymers. This type of structure enforces a highly stretched conformation of the polymer backbone and imparts unique properties due to low inter chain entanglement and low entropic penalty for self-assembly. The comb polymers have a diverse set of architectures and compositions with potential applications in surface modification, resin formulation and nanopatterning. To realize this potential, efficient, versatile and easy-to-handle synthetic methods need to be constantly evolved.This dissertation focuses on the synthesis of comb polymers based on a new monomer and the application of multi-component reactions to reduce synthetic complexity. The first part of this dissertation focuses on the design of a benign formamide monomer capable of undergoing isocyanide-based multi-component reaction. The synthesis, polymerizability, reactivity and stability of this monomer is studied, along with its utility in the synthesis of comb polymers. Specifically, a difunctional polymerizable initiator (Y-inimer) that can be used for two tandem controlled polymerizations is designed from the formamide monomer. The utility of this Y-inimer is demonstrated through the synthesis of a comb polymer with 1:1 ratio of A and B chains, and A/B mixed polymer brushes from a substrate where intimate contact between the A and B chains is beneficial for exploring polyelectrolyte behavior. Finally, a comb polymer-based block copolymer additive is explored for synergistically improving the toughness and strength of a 3D printable epoxy resin. The main contribution of this dissertation lies in the 1) design of benign monomer that can be used in isocyanide-based multicomponent reactions to design highly functional polymers, without having to directly handle the isocyanide, 2) development of a dual-functional polymerizable initiator for the synthesis of comb polymers with exact 1:1 ratio of A and B sidechains, and 3) development of a comb polymer additive for toughening of epoxy resin without loss of modulus or rheological properties.
