Process for producing amphipathic polymers

摘要

A process for producing polymers which comprises polymerizing an amphipathic monomer or copolymerizing an amphipathic monomer and another monomer which is copolymerizable therewith, wherein a polymerization solvent, a nonionic chain transfer agent and 1,1'-azobis(cyclohexane-1-carbonitrile) as a polymerization initiator are used together with the monomer. It is thereby possible to produce polymers with high hydrate formation and dissociation-controlling performance, and to produce polymers of low molecular weight with low residual monomer contents using the same amounts of polymerization initiators.
