Abstract
The zinc methacrylate copolymers with various monomer compositions were prepared for investigating the effect of zinc methacrylate (ZMA), 2-methoxyethyl acrylate (2-MTA) contents and compositions of ethyl acrylate (EA) and methyl methacrylate (MMA) as hydrophobic monomers on self-polishing behavior. The effect of molecular weight of the self-polishing copolymer (SPC) was also investigated. The characterizations of copolymers were performed by Fourier transform infrared spectroscopy (FTIR), 1H nuclear magnetic resonance (NMR), gel permeation chromatography (GPC), and differential scanning calorimetry (DSC). The leaching rate of SPC was determined from the reduction of dry film thickness after seawater immersion in a dynamic condition. The experimental results indicate the leaching rate of SPC can be controlled by monomer composition and molecular weight.
