FIELD: chemistry.SUBSTANCE: present invention relates to crystalline copolyester which can be granulated, used in adhesive compositions. Said copolyester consists of 20-50 mol % terephthalic acid, 20-50 mol % isophthalic and/or phthalic acid, 10-30 mol % linear aliphatic C-Cdicarboxylic acid, 1-20 mol % dimer of fatty acid and one or more glycols. Said copolyester can dissolve in non-halogenated and non-aromatic solvents with solid phase content of at least 30 wt %.EFFECT: obtained crystalline copolyester is soluble in non-halogenated and non-aromatic solvents with solid phase content of at least 30% and simultaneously has crystallinity which enables its granulation, and also has high adhesion to different substrates.8 cl, 2 tbl, 3 ex |
