Study on hydrolysis method of polyacrylamide with ultrahigh molecular weight
Jiurui Wang · 2002
Polyacrylamide with ultrahigh molecular weight is easily to degradate such as mechanical,chemical and thermal degradation,it make molecular weight descend.Because its MW is large to twenty millions,if macrocular chain of it have several cross-links,it may form hydrogels to make the solubility descend dramatically.The authors choose the reasonable condition to avoid the two reaction mentioned above,synthesize the part hydrolysis polyacrylamide with ultrahigh molecular weight.
