Compared to ordinary silicon resins, hyperbranched organosilicon resins have achieved significant improvements in both structure and performance. The term "hyperbranched" is derived from the unique molecular structure. 
In terms of structure, ordinary silicon resins are mostly linear or lightly cross-linked, with regular molecular chains but low branching degree. In contrast, hyperbranched organosilicon resins are formed through the introduction of multiple functional monomers and controlled polymerization, resulting in a highly branched three-dimensional molecular structure. There are numerous terminal functional groups in the molecule, and the molecular chains have less entanglement, presenting a more loose spatial configuration. 
The performance improvements are also remarkable. Ordinary silicon resins have poor solubility and require specific solvents for processing and have high viscosity. Hyperbranched structures have significantly improved solubility due to weak intermolecular forces. They can dissolve in various common organic solvents and have lower viscosity, resulting in better processing fluidity. Additionally, their terminal functional groups are abundant, allowing the resin to be functionalized for various properties such as antibacterial and weather resistance, while ordinary silicon resins have relatively simple functional properties. 
It is called "hyperbranched organosilicon resin" because the core lies in the highly branched topological structure of the molecule. This structure has a branching degree far exceeding that of ordinary branched polymers and presents a symmetrical tree-like structure, significantly different from traditional linear silicon resins. The "hyperbranched" term summarizes this structural feature, hence the name.
