Abstract
Acrylamide-dicyanodiamide macromer (M) is a new cationic condensation polymer of acrylamide (Am), dicyanodiamide (D), formaldehyde (F), and ammonium chloride with C=C as one of the end groups. Investigation on the kinetics of reactions between Am and F as well as D and F supported the suggestion about the polycondensation mechanism. In the synthesis of M, feed composition remarkly affected its molecular weight (M w ), and structure. The higher the ratio of Am/D, the lower M w , and a fraction of molecular chains contains more than one C=C
