Molecular formula :
nature : monomer by the gradual process of the formation of macromolecules reaction. Its basic characteristic is the reaction gradually, each step using the same basic mechanism and the same pace. Reaction began, quickly transformed monomer molecular weight is gradually increasing, every step, reaction products can exist independently, may separate. Ring as caprolactam monomer, or lactone ring ether containing active hydrogen atom or hydroxy activation occurred on the presence of polymerization to form amide polycaprolactone, polyether or polyester, isocyanate and Diol Addition gradually formed polyurethane response, it is gradually polymerization reaction. See ring-opening polymerization, the polymerization reaction.
