Metal Catalyzed

Metal-catalyzed simultaneous chain- and step-growth radical polymerization was examined to combine common conjugated vinyl monomers, such as various acrylates and styrene, as chain-growth monomers and various ester- or amide-linked monomers bearing both an unconjugated C=C bond and an active C–Cl bond as step-growth monomers. The CuCl/1,1,4,7,10,10-hexamethyltriethylenetetramine-catalyzed copolymerization of alkyl acrylates and various step-growth monomers at a 1 : 1-monomer feed ratio resulted in almost linear random copolymers that consisted of vinyl polymer and polyester units. Additional functional groups, such as oxyethylene and disulfide units, can be introduced into the main chain using a step-growth monomer that possesses the functional units between the unconjugated C=C bond and the active C–Cl bond. Copolymerization at a higher feed ratio of chain-growth monomers, such as alkyl acrylates and styrene, can provide multiblock vinyl polymers connected to the functionalized step-growth monomer units.

We report a facile ‘grafting from’ approach to graft copolymers with polyamide backbones and controlled vinyl polymer or polyester side chains. Two polyamides with in situ-formed pendant bromide or hydroxyl groups were obtained by Passerini-based multicomponent polymerization. They were used respectively to initiate the atom-transfer radical polymerization of vinyl monomers or the ring-opening polymerization of lactones to generate two new types of graft copolymers. One of the important features of the method is that the pendant initiators are generated in situ from non-branching monomers, and they are linked to the polymer backbone by ester bonds. Therefore, the vinyl polymer side chains could be detached from the backbones, and their structures could thus be fully characterized. Moreover, multicomponent polymerization and atom-transfer radical polymerization can even be carried out in a one-pot manner.

ABSTRACTThe metal-catalyzed step-growth radical polymerization was achieved to enable two systems for preparing tailored polymeric structures, i.e., sequence-regulated vinyl copolymer and periodically-functionalized polymer. The former is a novel strategy for preparing sequence-regulated vinyl copolymers by step-polymerization of sequence-regulated vinyl oligomers prepared from common vinyl monomers as building blocks. The later deals the simultaneous chain- and step-growth radical polymerization, which resulted in the polymers with periodic functional groups.

Polymer Chemistry: A Practical Approach in Chemistry has been designed for both chemists working in and new to the area of polymer synthesis. It contains detailed instructions for preparation of a wide-range of polymers by a wide variety of different techniques, and describes how this synthetic methodology can be applied to the development of new materials. It includes details of well-established techniques, e.g. chain-growth or step-growth processes together with more up-to-date examples using methods such as atom-transfer radical polymerization. Less well-known procedures are also included, e.g. electrochemical synthesis of conducting polymers and the preparation of liquid crystalline elastomers with highly ordered structures. Other topics covered include general polymerization methodology, controlled/"living" polymerization methods, the formation of cyclic oligomers during step-growth polymerization, the synthesis of conducting polymers based on heterocyclic compounds, dendrimers, the preparation of imprinted polymers and liquid crystalline polymers. The main bulk of the text is preceded by an introductory chapter detailing some of the techniques available to the scientist for the characterization of polymers, both in terms of their chemical composition and in terms of their properties as materials. The book is intended not only for the specialist in polymer chemistry, but also for the organic chemist with little experience who requires a practical introduction to the field.
