ISOCYANATE-TERMINATED PREPOLYMERS DERIVED FROM POLYETHER POLYOL MIXTURES HAVING LOW MONOL CONTENT AND THEIR USE IN POLYUREATHANE

摘要

Isocyanate-terminated prepolymers derived from polyether polyol mixtures having a low monool content are disclosed. This prepolymer is moisture cured or chain extended to produce polyurethanes with improved tensile strength, tear strength and reduced stress upon high elongation. The polyether polyol mixtures have a monool content of less than about 15 mole percent and an average hydroxyl functionality in the range of about 1.9 to about 2.4.
