A new initiation system for aqueous polymerization of acrylamide is presented.The effects of the contents of ammonia
urea
EDTA--2Na
pH value
concentration of monomer
polymerisation temperature in a Na2CO3 polymerization sysytem on the molecular weight of polymer and water-- soluble property were studied. Amethod to obtain the product with high molecualar weight which easily is dissolvedin water was found. A product in the form of powder with [η] = 22dl/g was obtained by Na2CO3 method.
