Step growth polymerization vs chain growth
網頁A step growth polymerization refers to a type of polymerization mechanism in which bi-functional or multifunctional monomers form first dimes, then trimers, oligomers and … 網頁Step-growth polymerizations can be divided into two lasses: condensation and addition polymerization. 1 In the case of a condensation reaction, two monomers combine with …

網頁Chain-growth polymerization involves 3 types of reactions : Initiation: An active species I* is formed by some decomposition of an initiator molecule I Propagation: The initiator fragment reacts with a monomer M to begin the conversion to the polymer; the center of activity is retained in the adduct. 網頁Here we compared the effects of chain-growth and step-growth polymerization for hydrogel crosslinking on the efficiency of protein release and diffusivity. For chain-growth …
