STUDIES ON CROSSLINKING MECHANISM BETWEEN TRIHYDROXYMETHYL PHENOL AND PARTLY HYDROLYZED POLYACRYLAMIDE
|
Abstract:
The structures of partial hydrolysis polyacrylamide samples crosslinked before and after by trihydroxymethyl phenol were characterized by~(13)C solid nuclear magnetic resonance(NMR) spectroscopy.The structures forming during self-crosslinking between hydroxymethyls and crosslinking between hydroxymethyl and primary amine were generated after reaction means two kinds of reactions were occurred.In further tracing test of infrared spectrometry(IR) and X-ray electron spectroscopy(XPS),the results of quantificat...
