查询词典 polymerization

Urushiol can be used as the basic raw material to develop economic and practical coating with good resistance to high temperature alkaline solution. Thus the polymer precursor was prepared using the polymerization of urushiol and formaldehyde. Then the urushiol-titanium chelate polymer (urushiol-Ti resin) was synthesized by way of the reaction of tetrabutyl titanate with the polymer precursor. The prospective target product was analyzed by means of high-performance liquid chromatography and Fourier transformation infrared spectroscopy.
