摘要
用嵌段聚合的方法合成了杂嵌型聚醚并用于废纸脱墨,研究了产物分子量对脱墨性能的影响。结果表明,较低分子量的杂嵌型聚醚(Mw<2000)具有良好的发泡性能,且脱墨效果优于整嵌型聚醚。
Block heteric polyethers with different molecular weight were synthesized by block polymerization method. The influence of molecular weight of polyether on the wastepaper deinking performace was studied. The results showed that such polyethers with low molecular weight (Mw〈2000) had good foaming properties and their deinking abilities were superior to those of all block polyethers.
