Description

Study is carried out of polypropylene fibers and fibrous carboxylic cationites on their base, which have been obtained by radiation graft polymerization of acrylic acid by the method of preliminary irradiation of polypropylene fibers on air (gamma-rays of 60Co, dose rate 0.37 Gy/s, dose 5-140 kGy). Mechanical and sorptive properties of polypropylene fibers and cationites are investigated after long-term storage in different conditions. The cationite obtained has excellent sorption properties towards cations of Cd, Pb, Cu. Zn, Fe and etc. It is shown that conditions of graft polymerization and storage influence on long-term stability of carboxylic cationites on the base of polypropylene fibers. It is pointed out that the use of cross-linking agent considerably increases long-term stability of grafted fibers

Abstract (Russian)

Изучены полипропиленовые (ПП) волокна и волокнистые карбоксильные катиониты на их основе, полученные путем радиационной прививочной полимеризации акриловой кислоты методом предоблучения ПП волокон на воздухе (гамма-лучи 60Co, мощность дозы 0,37 Гр/с, доза 5-140 кГр). Исследованы механические и сорбционные свойства ПП и катионитов через длительные сроки хранения в различных условиях. Полученный катионит обладает отличными сорбционными свойствами по отношению к катионам Cd, Pb, Cu, Zn, Fe и др. Показано, что на долговременную стабильность карбоксильных катионитов на основе ПП волокон влияют условия проведения прививочной полимеризации и условия хранения. Отмечается, что использование сшивающего агента значительно повышает долговременную стабильность привитых волокон
