Synthesis and Characterization of Self-Polishing Polyurethane Copolymers.

ABSTRACT

Synthesizing copolymers from Zn acrylate monomers is an effective strategy employed in the self-polishing materials industry. In this study, we designed and synthesized polyurethane-based self-polishing copolymers with improved surface adhesion properties. The synthesized polyurethane copolymers were characterized using Fourier transform infrared spectroscopy and inductively coupled plasma optical emission spectrometry. The properties of Zn-based polyurethane copolymers were compared with those of Zn-free polyurethane as reference. The erosion rates of the Zn-based polyurethane SPC films were determined by measuring changes in the film thickness after dynamic immersion tests. In comparison to Zn-free polyurethane, the Zn-based polyurethane self-polishing copolymers demonstrated effective self-polishing and surface adhesion properties.
