PAM-CA is hydrolyzed and coplymerized by vinylamide and cationic vinylacrylamide monomers. IR analysis indicates that carboxyl group(negatively charged) and vinyl group(positively charged) coexist on the PAM-CA chains. It is an amphoteric polymer with irregular configuration.

Main application:

• PAM-CA is a good profile control agent or water shut-off agent in oil drilling. It is more effective than any other ionic agent.
• PAM-CA is the newest flocculant for water treatment. It has been proved that in many cases combined use of PAMA and PAMC is more effective than use of either one. Generally combined use of PAMA and PAMC is needed to treat high surface tension samples, but improper use of the oppositely charged PAM may lead to white precipitates, thus rendering failure of treatment. PAM-CA is an ideal choice in this situation.It is simple, efficient and does not form precipitates. It is especially suitable for complicated or changing water samples.
• PAM-CA is more effective sludge dehydrating agnet than any other ionic PAM. Dehydrating agents are facing challenge that composition of waste water has become more and more complicated. Ionic PAM has been losing effects. PAM-CA that we provide has been proved to be more applicable, in dehydrating sludge from oil refinery and chemical plants.
• PAM-CA is more advantageous in papermaking than any other ionic PAM, especially as retention and filtration agents. It can increase the filtration speed and reduce the loss of fibres. It can also improve the smoothness and strength and help reduce side difference of paper.
