Reacting monomers
WebApr 3, 2024 · These monomers are generally very reactive molecules. The process in which monomers are all linked together to form the long-chain polymers is called a polymerization reaction or polymerization process. Classification of Polymerization Reaction WebAbstract. The catalytic hydrogenolysis of softwood lignins is normally conducted at temperatures below 200 °C but tends to provide monomer yields of less than 30 mol% as a consequence of the non-cleavable 4-O-5 and condensed (C–C) linkages of phenylpropane units in lignin.In the present study, catalytic hydrogenolysis at higher temperatures …
