ある。多量の親油性ビニル化合物の導入は。Generally, the transition temperature of an aqueous solution of a thermoreversible copolymer is
It can be controlled by a combination of types of vinyl compounds serving as structural units and their composition ratios. In this case, in the case of a copolymer in which the homopolymer is formed of two or more thermoreversible vinyl compounds, additivity often exists between the transition temperature of each homopolymer and its composition. Further, the homopolymer may copolymerize one or more thermoreversible vinyl compounds with one or more other copolymerizable non-thermoreversible vinyl compounds. As other copolymerizable non-thermoreversible vinyl compounds, one or more of hydrophilic vinyl compounds, ionic vinyl compounds, and lipophilic vinyl compounds can be employed. In that case, the introduction of these vinyl compounds changes the transition temperature of the aqueous copolymer solution, but in general, introduction of a hydrophilic vinyl compound increases the transition temperature, while introduction of a small amount of lipophilic vinyl compound lowers the transition temperature. It tends to go down. The introduction of large amounts of lipophilic vinyl compounds.
