Document Type and Number:
WIPO Patent Application WO/2018/103265
Kind Code:
A1
Abstract:
The present invention relates to a polyacrylate leveling agent, a preparation method and use thereof. The polyacrylate leveling agent has a chemical structure of formula (I), wherein the monomer (A) is one or more selected from the compounds having a chemical structure of formula (III), wherein R1 is hydrogen or methyl; R2 is a linear, branched or cyclic alkyl having a carbon atom number of 1 to 22, and the monomer (B) is one or more selected from ethylenically unsaturated compounds substituted with a functional group. In the presence of a telogen having a chemical structure of formula (II), the monomer (A) and a monomer (B) undergo RAFT living controllable radical polymerization, to obtain a polyacrylate leveling agent with a narrow molecular weight distribution. The leveling agent thus obtained, when applied to paint or ink system, can significantly improve coatability and anti-cratering ability of the coating, and wettability to substrate, and may also endow the coating film with smooth and anti-scratch effects. In addition, the preparation method is simple and easy for mass production.
