前言锰盐是纤维素和烯类单体接枝共聚的有效引发剂。H.Singh等用硫酸锰—硫酸为引发剂把烯类单体接枝到纤维素、织物、淀粉上。A.Heibiesh等用高锰酸钾在酸性溶液下把甲基丙烯酸甲酯或丙烯腈接枝到纤维素及其衍生物上。Ranby等用三价锰盐把丙烯腈接枝到纤维素或淀粉上,得到高吸水性的材料。国内也有用高锰酸钾在 Introduction Manganese salts are effective initiators for graft copolymerization of cellulose and vinyl monomers. H. Singh and other manganese sulfate - sulfuric acid as an initiator grafting vinyl monomers to cellulose, fabric, starch. A. Heibiesh and others use potassium permanganate to graft methyl methacrylate or acrylonitrile onto cellulose and its derivatives in an acidic solution. Ranby and others grafted acrylonitrile onto cellulose or starch with a manganic salt to give a highly water-absorbent material. Potassium permanganate is also useful in the country
