Disclosed is a degradable hyperbranched resin prepared from the following components in parts by weight: 1-100 parts of a cyclic monomer, 10-60 parts of an anti-fouling vinyl functional monomer, 5-60 parts of a difunctional monomer, 0-70 parts of a vinyl monomer, 1-20 parts of an initiator, 0.5-10 parts of a chain transfer agent, and 50-150 parts of an organic solvent. The difunctional monomer and the chain transfer agent are introduced during polymerization, so that a hyperbranched structure is prepared from a traditional linear polymeric anti-fouling resin and same is applied to the marine anti-fouling field for the first time. In addition, the resin further has the advantages of a high solid content and a low viscosity of a hyperbranched polymer, and the preparation method is easy and feasible, lower in cost, suitable for industrial production, and has good development prospects in the field of marine anti-fouling coatings.
本发明公开了一种可降解超支化树脂,由以下组分按重量份数制备而成:1-100 份环状单体、10-60 份防污乙烯基官能团单体、5-60 份双官能团单体、0-70 份乙烯基单体、1-20 份引发剂、0.5-10 份链转移剂和 50-150 份有机溶剂。在聚合过程中引入双官能团单体和链转移剂,从而在传统线性聚合防污树脂的基础上制备出超支化结构,并首次应用于海洋防污领域。此外,该树脂还进一步具有超支化聚合物固含量高、粘度低的优点,且制备方法简便可行,成本较低,适合工业化生产,在船舶防污涂料领域具有良好的发展前景。
