| 摘 要： | INTRODUCTIONWith the rapid changing of papermaking technology, such as elevated paper-machine speed, increased use of twin-wire former, further closed water circuit and increased use of recycled fibers, highly efficient paper chemicals, such as different kinds of polyacrylamides (PAM), are applied more and more widely to meet the challenge. Therefore, more and more studies on the characteristics of PAMs have been found. The PAM products with different molecular weig…

| Abstract: | In this paper, the cationic polyacrylamide(CPAM) with high molecular weight was prepared in aqueous solution through a complex initiator system. The CPAM was characterized by Fourier transform infrared spectroscopy (FTIR) and 13C nuclear magnetic resonance spectroscopy (13C NMR), and the charge density of the CPAM was determined by colloid titration. The results obtained indicated that the copolymerization technology used in the experiment was successful. |
