WebIn summary, a method for the direct polymerization of levulinic acid, diisonitriles, and different diamines via Ugi-4C8C reaction has been developed and optimized. The process was proved to be robust towards … WebThe monomer is the basic unit of a polymer. These monomers can bond to each other on each side, potentially forever. So this reaction of combining these monomers to form long chains or three-dimensional networks is known as polymerization. Broadly polymerization can be classified into two categories, Step-Growth or Condensation Polymerization
