通过丙烯酰胺、二氰二胺、甲醛及氯化铵的缩合反应,合成了分子链端含C=C双键的大单体,缩合过程用高压液相色谱考察,以AIBN为引发剂,二甲基亚砜为溶剂,使大单体与苯乙烯共聚,得到主链具有疏水性、侧链具有亲水性的共聚物,用GPC、IR光谱及溶解性对共聚物进行鉴定,苯乙烯含量较低时,共聚物溶于水,共聚物在MeOH/H_2O混合溶剂中的粘性行为表明它是带有疏水基团的聚电解质。 Through the condensation reaction of acrylamide, dicyandiamide, formaldehyde and ammonium chloride, the macromonomer with C = C double bond in the molecular chain was synthesized. The condensation process was investigated by high pressure liquid chromatography, AIBN was used as initiator, Methyl sulfoxide as solvent, the macromonomer and styrene were copolymerized to obtain a copolymer with hydrophobic backbone and hydrophilic side chain. The copolymer was identified by GPC, IR spectra and solubility. The styrene content At lower temperatures, the copolymer dissolves in water and the sticky behavior of the copolymer in a mixed solvent of MeOH / H 2 O indicates that it is a polyelectrolyte with hydrophobic groups.
