METHOD OF HARDENING DIENE POLYMERS HAVING FUNCTIONAL GROUPS, AND HARDENED DIENE POLYMER Russian patent published in 1998 - IPC

FIELD: chemistry of polymers. SUBSTANCE: claimed method comprises mixing diene polymer containing, as functional groups, at least 50 sterilely hindered olefinic epoxy groups per molecule, amino resins and proton hydrogen acid catalyst and subsequently hardening the whole on heating. The present invention is useful for preparation of sealants, adhesives and coatings which have lower wearing properties, increased smoothness and high physico- mechanical properties. EFFECT: more efficient hardening method. 14 cl, 6 ex, 1 tbl
