Summary


Macromonomers are oligo- or polymers fitted at one end with polymerizable group, most frequently styryl, metha- cryloyl or acryloyl. Copolymerization of macromonomers with suitable monomers leads to graft copolymers. Method toased on copolymerization of macromonomers has an advantage of mild reaction conditions, almost no limits in devising the structure of the main chain and the side-chains and controlling the frequency of grafts. Combination of rubbery main chain and thermoplastic side-chains gives thermoplastic elastomers. Such copolymers were obtained by copolymerization of e.g. butyl acrylate with polystyrene macromonomer. Coupling of hydrophobic main chain with hydrophilic side-chains leads to polymeric surfactants. They are made e.g. by copolymerization of polyethylene oxide) macromonomer with styrens. Incorporation of soluble, catalytically active side-chain into insoluble main chain matrix produces heterogenous polymeric catalysts. Combination of biodegradable main chain and biologically active side chains is employed in designing polymeric drugs, releasing the active substance when on target. A number of macromonomers based on biologically active polymers (e.g. polypeptides or enzymes fitted with a polymerizable group) have already been prepared and copolymerized..
