Properties of new carboxymethylcellulose-based graft copolymers as oilfield drilling-mud additive with multifunctions

摘要

New carboxymethylcelluslose-based graft copolymers with amphoteric character have been synthesized by grafting 2-(dimethylamino) ethyl methacrylate (DMAEMA) onto carboxymethylcellulose (CMC) using persulfate (APS)-initiated solution polymerization tehcnique (Table 1).
