ADHESIVE COMPOSITION BEING SUBSTITUTED BY FUNCTIONAL GROUPS, STELLATE BLOCK COPOLYMER OF STYRENE-ISOPRENE AND METHOD FOR ITS PRODUCTION

摘要

FIELD: production of resins having predetermined properties. SUBSTANCE: proposed composition contains stellate three-beam copolymer, its beams represent styrene-isoprene blocks. Average molecular weight of polystyrene blocks is lower 30000, usually it is within 7000-30000 ranges, total molecular weight of said block copolymer is within 120000-250000. EFFECT: improves quality of desired composition.
