WebSep 5, 2013 · Actually, the reactivity of SR-10 varies depending on the monomers. SR-10 can be polymerized easily with BA, 2-EHA, MMA, EA and VAc. The monomer’s Q and e values (Table 3), and solubility in water (Table 4) create the difference in reactivity with SR-10. Acrylic monomers are highly reactive because they are electron acceptors (e>0). WebMonomers may be classified as ‘hard’, ‘soft’, or ‘reactive’, based on the properties they confer on the final polymer or copolymer. Hard monomers are, for example, methyl methacrylate, …

WebJan 13, 2024 · Amino acids like glutamic acid are examples of monomers. A monomer is a molecule that forms the basic unit for polymers, which are the building blocks of proteins. Monomers bind to other monomers to form repeating chain molecules through a process known as polymerization. Monomers may be either natural or synthetic in origin. WebMost direct copolymerizations of equimolar mixtures of different monomers give statistical copolymers, or if one monomer is much more reactive a nearly homopolymer of that monomer. The copolymerization of styrene with methyl methacrylate, for example, proceeds differently depending on the mechanism.

WebReactivity of monomers This is a relative value derived from measurements of the rate of monomer addition to a specific active centre. [Pg.45] Many attempts have been made to define monomer reactivity by some numerical value, and to find relations suitable for relating this value to monomer structure. WebMethacrylate monomers are prone to depropagate which is the opposite reaction to chain growth and is therefore slowing the polymerization rate. At lower monomer concentrations, it becomes significant enough to halt the polymerization. Acrylate monomers do not exhibit this behavior; however, they are characteristic for transfer to polymer reactions.
