Title:
BRANCH-POINT-BREAKING-TYPE HYPERBRANCHED RESIN, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/008604
Kind Code:
A1
Abstract:
Disclosed are a branch-point-breaking-type hyperbranched resin, a preparation method therefor, and the use thereof. The branch-point-breaking-type hyperbranched resin is prepared mainly from the following components in parts by weight: 0-70 parts of an anti-fouling vinyl functional monomer, 1-60 parts of a difunctional monomer, 0-90 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. Branch points of the resin can be broken under the attack of seawater, and after breakage, small molecular fragments that are easily absorbed by the environment are formed, so that marine microplastic pollution can be effectively avoided. Moreover, pendant silane ester bonds/zinc ester bonds/copper ester bonds/betaine-type zwitterionic precursors can also be hydrolyzed in seawater, which, in cooperation with the breakage of the branch points, can further increase the hydrolysis rate of a material, achieving rapid polishing, thereby solving the problem of traditional self-polishing materials being dependent on ship speed. Same satisfies static anti-fouling requirements in sea areas where fouling pressure is high.
