多组份含金属盐透明树脂的合成

本文将双烯聚醚砜大分子单体(BPS-MA)引入含金属(Pb、Ba等)盐单体的苯乙烯体系中进行聚合,发现单体配比与树脂透明性密切相关。对于Pb(MA)_2/St/MA/BPS-MA四元体系,欲获得透明树脂,BPS-MA用量大于20％时,摩尔比MA/Pb(MA)_2]可由原来的5.5降至2.2左右,并且可获得n_D>1.60的透明材料。光学性能测试结果表明,Pb(MA)_2、BPS-MA量增加,n_D增大,阿贝数v_D略降低;MA量增加,n_D下降v_D略增加。适当的配比可望制备出性能优异的多组份含金属盐透明聚合物材料。

SYNTHESIS OF MULTICOMPONENT METAL CONTAINING TRANSPARENT RESIN

High reactive bisvinyl macromonomer (BPS-MA) introduced into the system of styrene, methacrylic acid and metal salts of monomers, the reactivity of the system can be regulated by adjusting the content of BPS-MA. The study of relationship between monomer ratio and resin transparency shows that without BPS-MA in the system, at the ratio of methylacrylic acid vs Pb monomer MA/Pb(MA)2>6. 0, transparent resin can be obtained; BPS-MA 20%, MA/ Pb(MA)2 2. 2, transparent resin with high refractive index (nD>-1. 60), can be obtained. The study of optical properties indicates that with the ratio of Pb(MA)2, BPS-MA increases, nD of the resin will increase but Abbe number VD will decrease; the ratio of MA increases. nD decrease , VD decreases a little. At certain ratio of the monomers, multicomponent metalcon-taining transparent polymer materials can be reached, which has excellent properties.
