Explanation

It is also called radiative polymer. It refers to the macromolecule with 5 or more macromolecule chains connected to the same point at one end. The mountain star core and arm are composed. The star core is generally a low molecule, which is composed of parts from initiator and coupling agent molecules. The emitted polymerization molecular chains are called arms. Each arm can be the same or different. According to this, it can be divided into symmetric and asymmetric types. The number of arms is usually 36. The star core containing multiple functional groups can increase the arm K through polymerization, or prepolymer macromolecules can be connected to the star core through active end groups. star polymer is characterized by low melting viscosity and solution viscosity when its molecular weight is the same as that of general polymer, which is easy to process.
