INTRODUCTION (abstract of PhD thesis) 
The aim of the research work is synthesis of ionogenic polymers (IP) and the 
development of polymer compositions with effective salt-washing features in saline soils 
based on them.
The objects of the research work are unsaturated carboxylic acids, polyfunctional 
synthetic polymers, polymer composition "Biosolvent", soil samples, cotton and tomato 
seedlings.
Scientific novelty of the research work: 
polymaleic acid and its copolymer with a molecular weight of 2000-5000 Da, easily 
and rapidly soluble in water, with a biodegradable property based on maleic anhydride and 
acrylic acid were synthesized, the dependence of the synthesis conditions on the molecular 
weight of the polymer obtained was revealed; 
polymer composition (“Biosolvent”) of ionic nature was developed based on 
synthesized homopolymers and copolymers and the composing components of IP, surfactant 
and gently neutralizing were selected; 
modern physico-chemical methods were developed for analyzing the components of 
the composition and the shelf life was identified by the method of rapid wear and physico-
chemical methods; 
it was found under the influence of the composition, total saline salt effective washes 
by 35-40% compared to control, and soil porosity increases by 20-30%; 
stimulating effects "Biosolvent" preparation and its individual components on growth 
and development of seed, soil microflora, dynamics of the number of microorganisms were 
determined;
