Explanation
depolymerization is the reverse process of chain polymerization, also known as chain degradation or chain degradation. polymer is completely transformed into monomer in the process of degradation reaction. Under the influence of oxygen or various physical factors (heat, light, irradiation, mechanical force, etc. depolymerization is particularly easy to be carried out above the upper limit temperature of polymerization. In industry, high polymer waste is often depolymerization at a higher temperature to achieve the purpose of recycling. For example, polymethyl methacrylate can be completely depolymerization to monomer at 270 ° C.
