FIELD: chemistry. n SUBSTANCE: present invention relates to a polyester polyol, an adhesive two-component polyurethane system and an adhesive. Polyester polyol has a structure of formula (II) in which R 1 and R 2 independently denote hydrogen, methyl or ethyl, m equals 1 to 15, n equals 2 to 20, and R denotes C 1 -C 4 -alkyl group. Said adhesive system contains polyol component (a) containing from 0.2 to 100 wt. % of polyester polyol of formula (II), and (b) prepolymer containing end isocyanate group. Adhesive contains a prepolymer containing a terminal isocyanate group containing units of formula (II). n EFFECT: present invention overcomes difficulties associated with phase separation of silanes. n 6 cl, 10 tbl, 25 ex |
