FIELD: chemistry.
SUBSTANCE: invention relates to novel compositions containing (a) anionic block-copolymers of monoalkenylarenes and conjugated dienes, where one of the blocks is characterised by controlled distribution of monomer links of the copolymer of conjugated diene and monoalkenylarene and demonstrates specific assembly of monomers in the copolymer block, and (b) special-purpose softening modifiers having a specific structure. The invention also discloses methods of preparing said novel compositions and different versions of final use and field of using said compositions.
EFFECT: improved fluidity, reduced hardness, improved stress relaxation characteristics of the polymer compositions, which makes them especially attractive for use in personal hygiene purposes where nonwoven materials, elastic films and fibres are used.
