Description
上記の高分子化合物は単独でも、他の単量体と共重合（例えばランダム共重合）させて得たものでも良い。共重合する単量体としては、親水性単量体、疎水性単量体のいずれも用いることができる。一般的にポリＮ置換（メタ）アクリルアミド誘導体の曇点は親水性単量体と共重合すると上昇し、疎水性単量体と共重合すると下降する。従って、これらを選択することによっても、所望の曇点を有する高分子を得ることができる。ここで用いる親水性単量体、疎水性単量体も上述したその水溶液が曇点を有する高分子（Ｂ）の場合と同様である。 The above polymer compound alone, or may be those obtained, dried (random copolymerization Polymerization In example embodiment) copolymerized with other monomers. As the monomer to be copolymerized, either a hydrophilic monomer or a hydrophobic monomer can be used. In general, the cloud point of a poly-N-substituted (meth) acrylamide derivative increases when copolymerized with a hydrophilic monomer and decreases when copolymerized with a hydrophobic monomer. Therefore, a polymer having a desired cloud point can also be obtained by selecting them. The hydrophilic monomer and hydrophobic monomer used here are the same as in the case of the polymer (B) in which the aqueous solution has a cloud point.
