大孔的苯乙烯-二乙烯苯共聚物经氯甲基化后,分别与乙酰丙酮镍、乙酰丙酮钠和四正丁基乙酰丙酮铵三种不同的乙酰丙酮盐反应,可制得聚3-(p-乙烯苄基)戊二酮-[2,4]。其中以由乙酰丙酮镍制得的聚合物最好,除二乙烯苯外,78%左右的苯环乙酰丙酮化了。该聚合物螯合Fe~(3+)和Ni~(2+)的能力与β-二酮基高聚物相仿或稍优。还比较了此类高聚物的物理机械性能。 Macropore styrene - divinylbenzene copolymer by chloromethylation, respectively, with acetylacetone nickel, acetylacetonate and tetra-n-butyl acetylacetonate acetylacetonate three different acetylacetonate reaction can be obtained poly 3- (p-vinylbenzyl) pentanedione- [2,4]. Among them, the polymer obtained from nickel acetylacetonate is the best, and about 78% of acetylacetone is acetylated with divinylbenzene. The chelating ability of Fe ~ (3+) and Ni ~ (2+) is similar or slightly better than that of β-diketopolymer. The physical and mechanical properties of such polymers are also compared.
